In the dramatic style of online media pumping the RSS feeds with USB juice jacking end of days, consider this satirical word salad.

The domain of USB juice jacking unfurls its potentially ugly head with an available open socket in the dark corner of an airport corridor. Both consumers and enterprise travels could run the high risk of an orchestrated series of pragmatic events leading to the downfall of one’s sanctuary… or could it? The bedrock principle here is that USB juice jacking grievous – but the true question, is it? Or is this all just media hype?

Consider these avenues to preserve the sanctity of your data and the haven of your device:

The Portable Paragon: Opting for a portable charger takes the sting out of the juice jacking quandary. By sidestepping public charging stations, you effectively dodge the peril. Anticipating the untimely depletion of batteries, especially during journeys, beckons the wisdom of an emergency charging repository. A small caveat: ensure this fortress is adequately fortified prior to your ventures, and that its compatible conduits stand ready.

The Cord-And-Plug Ballet: If the portable charger is but a distant memory, there’s a dance of cords and plugs that could spare you the dance with danger. Brandishing your personal USB cable and trusty outlet plug allows you to plug into a wall socket, rendering the jeopardy null. When sockets prove elusive, your own USB cord at a public station unfurls as an emergent bastion.

Taming the Data Hydrant: Enter the esoteric inner workings of USB cables, and you’ll uncover a binary nature – a power-bearing filament and a data-carrying cousin. The crux of juice jacking unravels through the latter. Presenting a savior: a USB cable that forsakes data aspirations. This averts the artifice. But do heed the fine print: scenarios beckon where data-hungry cables are indispensable – such as shuttle duties to the cloud. Be prepared for a multiplicity of cords and the vigilance to discern their roles.

Sentinel of Data: The data blocker, a digital sentinel of sorts, takes its stance here. It forms an impervious bulwark between your cord and the dubious charging station. A strategic interlude that both the cord and the data pins traverse. These wards negate the data transmission, while the coursing power remains uninterrupted. Similar to their data-agnostic counterparts, they preclude the ingress of malware and data subversion.

Mistrusting the Digital: “Trust” and “share data,” an innocent query from your device as you court a public charger. Swiftly recoil. Apple’s devices, astutely attuned to data traffic, wave a flag of caution. This prompts a swift retreat when encountered. Such a message signals an imposter and hints at the lurking specter of juice jacking.

The Ordeal of Juice Jacking in the Corporate Landscape

The saga of USB juice jacking, while impactful on personal devices, weaves a more perilous tapestry within corporate enclaves. Envision the cataclysm: a sprawling data breach, gestating within the confines of a juice jacking event. A corporate warrior connects their laboring device to a public charger, unwittingly offering a foothold. In an instant, cyber marauders could storm the ramparts of the employee’s corporate realm.

For the prudent corporation, a trinity of strategies beckons:

Enlighten the Digital Denizens: Infuse your workforce with the intricacies of juice jacking. Cultivate a cybersecurity ethos, emboldened by informed choices in the face of electronic deceit.

Outfitting the Expeditionary: Equip your corporate wanderers with data blockers – their digital exoskeletons against the lurking threats of public charging.

The Clarion Call of Vigilance: If suspicions of malware assail employees in the embrace of a public charging portal, mandate the clarion call for reporting. Swift response translates to remote data purging, a bulwark against further inroads into corporate dominion and the treacherous terrain of data breaches. Inculcate an understanding of the virtue of vigilance, even in the face of policy breaches, to circumvent further havoc.

In the quest to comprehend juice jacking, one often veers to extremes: a hyperawareness that presumes its omnipresence or a dismissive attitude that fuels complacency. Opting for the middle path, however, stands as the beacon of wisdom. Acknowledge the potential and attendant risks, and embrace a precautionary stance. Thus ensues a realm where both you and your workforce can replenish your devices without courting catastrophe.

Western Digital is not answering questions about their failed SSD drives because they don’t know exactly where the problem lies. The three main components for any SSD drive will be the PCB board, the on-board chipset that controls the flow of information between the host PC and the memory and of course, the NAND memory itself. If we break this down a bit more, we might find out what the reason is.

Background (PCB, USB Controller, NAND Memory)

The PCB board

Printed Circuit Boards, or PCBs, play a vital role in modern electronics. They are like the backbone of electronic devices, providing a platform for components to be connected, organized, and powered. Let’s break down their value, design process, testing, and impact on soldered components.

Value of PCBs:
A PCB serves as a foundation for electronic components to work together. It’s like a puzzle board with electrical pathways etched onto it, allowing components like resistors, capacitors, microchips, and more to communicate and function properly. Without PCBs, it would be incredibly difficult and messy to manually connect all these components together.

Designing PCBs:
The process of designing a PCB involves several steps:

Schematic Design:
Engineers create a schematic diagram, which is like a blueprint showing how components are connected. This helps plan the layout of the PCB.

PCB Layout:
Using specialized software, the engineer arranges components on the PCB, considering factors like size, heat dissipation, and signal integrity. This layout involves placing components and drawing the electrical pathways (traces) that connect them.

Routing:
This step involves deciding the exact paths for the traces to minimize interference and ensure efficient operation. High-speed components may require careful consideration to maintain signal quality.

Layers:
PCBs often have multiple layers, allowing for more complex designs. Each layer can carry different traces, making the most of the available space.

Components:
Once the layout is finalized, components are attached to the PCB using soldering techniques. Surface Mount Technology (SMT) and Through-Hole Technology (THT) are commonly used methods.

Testing PCBs:
Testing ensures that the PCB functions as intended and helps catch any errors before mass production. There are a few ways to test PCBs:

Visual Inspection:
Engineers visually check for any obvious issues such as soldering defects or incorrect component placement.

Continuity Testing:
This involves checking if the expected electrical connections exist between components and traces. Multimeters can help with this.

Functional Testing:
PCBs are powered up, and their performance is checked to ensure that all components are working as expected. This can involve running specific test programs or performing specific tasks to evaluate functionality.

Impact on Soldered Components:
Components soldered to a PCB are connected to it through solder joints. These joints are vital for the proper functioning of the device. The quality of soldering affects the overall reliability and performance of the PCB. Poor soldering can lead to bad connections, signal interruptions, and even complete device failure.

PCBs are crucial for modern electronics as they provide a structured platform for components to work together. Their design involves careful planning, layout, and routing of components and traces. Testing ensures proper functionality, and the quality of soldered components directly impacts the overall reliability and performance of the PCB and the device it’s a part of.

USB Controller

Let’s dive into USB controllers and their role in solid-state hard drives (SSDs) and flash drives.

The Chinese government recently took a significant step against an American semiconductor company Micron Technology with corporate headquarters in Boise, ID. The Cyberspace Administration of China announced that Micron, one of the largest producer of memory chips in the world, posed significant security risks to China’s critical information infrastructure supply chain. As a result, it ordered operators of critical national infrastructure to refrain from purchasing Micron’s products.

Experts believe that Micron became an apparent target for China due to its technology, which could be more easily replaced with chips from South Korean competitors such as Samsung and SK Hynix. In fact, just last month, the White House requested that South Korea’s chipmakers refrain from filling any market gap in China if the sale of Micron’s products were to be restricted.

China conveyed its decision to Micron during a meeting held in Beijing on Sunday.

Could this be backlash for the United States restricting Huawei products within its borders due to concerns over security risks? If you remember, the ban was implemented to protect the country’s critical information infrastructure from potential threats posed by Huawei’s technology. Several factors contributed to this decision.

One of the primary concerns is the alleged close relationship between Huawei and the Chinese government. There have been suspicions that Huawei’s equipment could potentially be used for unauthorized surveillance or cyberattacks, posing a threat to national security. The fear is that the Chinese government could exploit vulnerabilities in Huawei’s technology to gain access to sensitive information or disrupt critical networks.

Furthermore, the ban on Huawei products is also driven by concerns about intellectual property theft. The United States has accused Huawei of stealing trade secrets and engaging in unfair business practices, leading to legal disputes and a deterioration of trust between the two nations.

The US government has taken measures to protect its communication networks by restricting the use of Huawei equipment. These actions have included banning federal agencies from purchasing Huawei products and urging allies to follow suit. The concern is that relying on Huawei’s infrastructure could compromise the integrity and security of the country’s telecommunications networks.

Micron Technology, a company that makes computer memory, experienced a nearly 5% increase in its stock price during early trading on Thursday. The reason for this boost is Micron’s announcement that it will introduce an advanced technology called extreme ultraviolet (EUV) in Japan. This technology will be used to produce the next generation of dynamic random access memory (DRAM).

Micron, headquartered in Boise, Idaho, stated that it is the first chip company to bring EUV technology to Japan for manufacturing. The company will be assisted by its facility in Hiroshima. Micron plans to invest up to $3.63 billion in the process over the next few years, with support from the Japanese government. The aim of this investment is to facilitate further technological advancements, particularly in emerging areas such as generative artificial intelligence applications.

Micron’s President and CEO, Sanjay Mehrotra, expressed his pride in being the first to implement EUV technology in Japan. He emphasized the significance of developing and producing 1-gamma at the Hiroshima facility. Mehrotra also acknowledged Micron’s commitment to Japan, its strong relationship with the Japanese government, and the exceptional skills of the Micron Hiroshima team.

Extreme Ultraviolet (EUV) technology is an advanced manufacturing technique used in the production of semiconductor devices, such as computer chips. It involves the use of extremely short-wavelength light, specifically in the range of 13.5 nanometers, which falls within the extreme ultraviolet part of the electromagnetic spectrum. EUV light has much shorter wavelengths than the ultraviolet light used in conventional chip manufacturing processes.

EUV technology offers several advantages over traditional lithography methods. The shorter wavelength of EUV light enables higher precision and resolution in creating smaller and more intricate circuit patterns on silicon wafers. This allows for the production of denser and more powerful semiconductor devices. Additionally, EUV technology reduces the complexity and number of process steps required in chip manufacturing, leading to increased efficiency and cost-effectiveness.

Implementing EUV technology in semiconductor fabrication requires specialized equipment and processes. It involves using a powerful EUV light source to project a pattern onto a silicon wafer coated with light-sensitive materials, known as photoresist. The pattern is transferred onto the wafer, forming the intricate circuitry and structures that make up the semiconductor device.

EUV technology represents a significant advancement in the semiconductor industry and enables the development of smaller, faster, and more energy-efficient chips. It plays a crucial role in meeting the increasing demand for higher-performing electronic devices and paves the way for future technological innovations.

Starting in 2025, Micron plans to gradually incorporate EUV technology into its manufacturing processes in Taiwan and Japan, specifically in the 1-gamma nodes.

Rahm Emanuel, the U.S. ambassador to Japan, highlighted the importance of the partnership between Micron and Japan, stating that it represents a significant advancement in securing the semiconductor supply chain. Emanuel also emphasized the potential for economic growth and security through collaboration in cutting-edge technologies.

The announcement follows reports that Japanese Prime Minister Fumio Kishida was scheduled to meet with executives from various semiconductor companies, including Micron, to strengthen cooperation in the industry.

During a press conference on Wednesday, Chief Cabinet Secretary Hirokazu Matsuno emphasized that the semiconductor supply chain cannot be established by a single country alone. He stressed the importance of collaboration with like-minded countries and regions to achieve this goal.

Western Digital, an Irvine CA based company who makes digital storage devices and technology, recently revealed that they experienced a security issue on March 26. An unauthorized person gained access to some of their systems without permission. As a result, Western Digital took many of their servers offline, which caused problems for customers who couldn’t access their data remotely.

As you can guess, everyone is concerned. Joseph Carson, who is a security scientist, said that it’s a reminder of what can happen when attackers gain access to a company’s network. He pointed out that since Western Digital is a cloud storage company with many customers, the impact of the breach is even greater because many consumers and businesses couldn’t access their important data remotely.

Tom Kellermann, a cyber strategy expert, shared similar worries. He called this a significant supply chain attack, which means that it could have a widespread impact on e-commerce. He also mentioned that if this attack was done by a rogue nation state, it could have national security implications that last for months.

On the positive side, Erich Kron, an advocate for security awareness, praised Western Digital for quickly addressing the issue and being transparent about it. He also said that it’s important for organizations to have a plan to deal with network attacks that could lead to ransomware, a type of malicious software that can lock up data until a ransom is paid. Kron mentioned that many of these attacks happen because of human error, so it’s important for employees to be trained and educated about how to spot email phishing attacks and other tricks used by hackers.

Western Digital said that they are working with law enforcement authorities to investigate the incident, and they will provide updates as more information becomes available.

Western Digital experienced a security breach that affected their systems and caused disruption for their customers. Experts are concerned about the impact of this breach and emphasize the importance of organizations having plans in place to deal with network attacks. Western Digital is actively investigating the incident and working with authorities to resolve the issue.

Western Digital is a company that manufactures data storage devices, including flash drives, SSD hard drives, server and IT solutions. Flash drives are small devices that can store and transfer data, such as documents, photos, and videos. Western Digital uses advanced technology to create USB flash drives by integrating memory chips, controllers, and other components into a compact and portable design. The memory chips store data in a way that allows it to be quickly accessed and transferred. The controllers manage the flow of data between the memory chips and the device it’s connected to, ensuring smooth operation. Western Digital follows strict quality control and testing processes to ensure that their flash drives are reliable and durable. Once the flash drives are manufactured, they are packaged and distributed to retailers for sale to consumers and businesses for various data storage needs.

Update — As of Sep 2025

Quick rewind: in April 2023, the U.S. Justice Department announced a settlement with Micron over an Immigration and Nationality Act hiring violation — back pay of $85,000 to the affected worker, a civil penalty, required training, policy fixes, and a two-year monitoring period. That clock started then. :contentReference[oaicite:0]{index=0}

As of April 2025, that two-year window has run its course. The DOJ’s public materials haven’t flagged any extension or follow-on enforcement tied to this matter — which, in plain English, suggests Micron did what it said it would do and the government didn’t see cause (so far) to push further. :contentReference[oaicite:1]{index=1}

A small footnote worth keeping: while DOJ press language didn’t specify the penalty amount, multiple industry/legal summaries pegged the civil penalty at $4,144, alongside the $85,000 back-pay figure. Think of that as the “administrative sting,” with the real teeth being training, policy changes, and monitoring. :contentReference[oaicite:2]{index=2}

Morris take: compliance isn’t a finish line; it’s a treadmill. Micron has been broadcasting governance and ethics updates in 2025 filings and sustainability materials — the right kind of noise if you’re trying to keep regulators, customers, and investors calm. No drama beats new drama every time. :contentReference[oaicite:3]{index=3}

The Justice Department has reached a settlement with Micron Technology Inc., headquartered in Boise, Idaho, after finding the company violated the Immigration and Nationality Act (INA). The case centered on allegations that Micron discriminated against a U.S. citizen during hiring by favoring a temporary visa holder instead.

The investigation began after a U.S. citizen filed a complaint claiming he was unfairly denied a job. Federal investigators confirmed that Micron had chosen a temporary visa worker without fully considering the citizen’s qualifications. Under the Immigration and Nationality Act (INA), employers are prohibited from discriminating against job applicants based on citizenship, immigration status, or national origin unless specifically required by law.

As part of the settlement, Micron agreed to pay a civil penalty to the U.S. government and provide $85,000 in back pay to the affected worker. In addition, the company must retrain its staff on INA’s anti-discrimination rules, update hiring policies, and submit to federal monitoring for two years.

The Immigrant and Employee Rights Section (IER) of the Justice Department’s Civil Rights Division enforces the INA, which protects workers from discrimination in hiring, firing, recruitment, and employment eligibility verification. It also prohibits unfair documentary practices, retaliation, and intimidation. Assistant Attorney General Kristen Clarke underscored that the Department will hold companies accountable for violations regardless of their size or industry.

This settlement is a reminder that compliance with civil rights laws must go hand in hand with corporate hiring practices, especially for companies as large and visible as Micron, a global leader in semiconductors and memory products.

Micron memory solutions include both DRAM and NAND flash memory. DRAM provides high-speed, temporary storage for active data and is critical in applications such as gaming, cloud computing, and enterprise workloads. NAND flash memory, a non-volatile technology, is widely used in SSDs, memory cards, and USB flash drives for long-term data storage. These technologies are key components in smartphones, servers, and data centers worldwide.

Known for reliability and energy efficiency, Micron’s products continue to power a range of industries—from automotive systems to consumer electronics and industrial automation—making the company a cornerstone in today’s digital infrastructure. While the lawsuit highlights compliance issues, it does not change Micron’s global reputation as a major innovator in memory and storage solutions.

Kioxia Holdings Corporation, abbreviated as Kioxia and stylized as KIOXIA, is a Japanese-American multinational computer memory manufacturer headquartered in Tokyo. In June 2018, Toshiba Memory Corporation was spun off from the Toshiba conglomerate. On March 1, 2019, it became a wholly owned subsidiary of Toshiba Memory Holdings Corporation and was renamed Kioxia in October 2019

While still a subsidiary of Toshiba, the company was credited with inventing flash memory in the early 1980s. The company is expected to have 18.3% of the global revenue share for NAND flash solid-state drives in the second quarter of 2021. Kioxia Corporation’s parent company is this one.

Fujio Masuoka, an engineer at Kioxia predecessor Toshiba, invented flash memory in 1980, and Masuoka and his colleagues presented their NOR flash invention in 1984.

Toshiba Corporation completed its acquisition of OCZ Storage Solutions in January 2014, renaming it OCZ and making it a Toshiba brand.

Toshiba Memory Corporation was spun off from Toshiba Corporation on June 1, 2018, due to heavy losses incurred by the bankruptcy of former parent company Toshiba’s Westinghouse subsidiary over nuclear power plant construction at Vogtle Electric Generating Plant in 2016. Toshiba retained 40.2% ownership of the new company. Toshiba’s memory businesses were all merged into the new company. On March 1, 2019, Toshiba Memory Corporation became a subsidiary of the newly formed Toshiba Memory Holdings Corporation.

Kioxia suffered a power outage at one of its factories in Yokkaichi, Japan, in June 2019, resulting in the loss of at least 6 exabytes of flash memory, with some sources estimating the loss to be as high as 15 exabytes. Western Digital used (and continues to use) Kioxia’s facilities to manufacture its own flash memory chips.

KV-CSD is an acronym for Key Value Store Computational Storage Device and Hynix a NAND memory manufacturer is directing their technology towards this storage approach.

Here at GetUSB.info we focus on NAND memory and typically look at the write speeds of devices. However, for data centers and analytic companies, the ability to retrieve data is more important. The ability to read the index of where data is and then retrieve it is a key part for data analytics and how companies can react to queries.

Just imagine something like an insurance company holding millions of policies and related customers who need to search and sort through large amounts of data quickly while servicing customers… now imagine that same requirement during a natural disaster where the incoming requests skyrocket. Quickly finding the data needed becomes a mission critical task.

Traditional methods for indexing are “relationship databases” and done on a file-record level. A file-record indexing approach uses predefined data structures in the database as a series of tables containing data about the type of information related to the files, like meta-data tags.

In contrast, key–value systems treat the data as a single transparent collection which can have many different values for each record in a column structure. The indexing values in a column provide a more efficient method to search the indexed data to more efficiently find the requested data.

What Hynix is doing is introducing a method to index content on the fly (as it’s being written) into NAND memory so when a subsequent search is performed the result will present itself more quickly.

Hynix teamed with Los Alamos National Laboratory in Northern New Mexico who is a multidisciplinary research institution engaged in strategic science on behalf of national security, and managed by Triad, a public service-oriented, national security science organization equally owned by its three founding members: Battelle Memorial Institute (Battelle), the Texas A&M University System (TAMUS), and the Regents of the University of California (UC) for the Department of Energy’s National Nuclear Security Administration.

Los Alamos enhances national security by ensuring the safety and reliability of the U.S. nuclear stockpile, developing technologies to reduce threats from weapons of mass destruction, and solving problems related to energy, environment, infrastructure, health, and global security concerns.
