NOR based flash has long erase and write times and has a full address/ data interface.Â Meaning one can read or write data to any portion of the NOR chip.Â The NOR technology is mostly used for low levels of read/write cycles.Â So for example, NOR is great for BIOS and firmware of a device.Â NOR was the first version of flash, but everyone quickly realized a cheaper, faster solution is also needed. In 1989 the first NAND flash chip was introduced.Â It had faster erase and write times, higher density, and lower cost than NOR flash – with ten times the endurance. The draw back with NAND [if you can call it that] is the I/O interface only allowing sequential access to data. Meaning you can only write to the device after the last bit of data has been written.Â This makes it suitable for mass-storage devices such as PC cards and various memory cards like USB, SD and microSD, and somewhat less useful for computer memory.

To start, the SD media is broken down into “Classes”Â The Class depicts the speeds at which a device reads and writes.
SD Cards and SDHC Cards have Speed Class Ratings defined by the SD Association. The SD Speed Class Ratings specify the following minimum write speeds based on “the best fragmented state where no memory unit is occupied”:
- Class 2: 2 MByte/s – 13x
- Class 4: 4 MByte/s – 26x
- Class 6: 6 MByte/s – 40x
Well that might change because Samsung is entering the retail market with their solid state flash of Secure Digital, Compact Flash and microSD media. Samsung will release sizes from 4GB to 16GB capacity before the end of 2009.Â These cards will be in the â€˜Plusâ€™ memory card class and compliant with the Secure Digital class 6 performance standards.Â Cards boust a speed range of 17Mbps to 45Mbps.

The DP-004 can record two sources at once to the included 1GB SD Card. A built-in stereo condenser microphone makes it simple to record anywhere you go, perfect for concerts, rehearsals and songwriting inspirations. A pair of 1/4″ jacks on the rear panel allow you to connect your own microphones or sources. You can even switch the inputs to guitar level for recording. You can connect to the Pocketstudio via two 1/4″ mic line inputs, switchable guitar input, headphone line out or USB 2.0 connection. For recording options you have four track digital multitrack recording with 44.1kHz/16-bit WAV recording.Â The unit records directly to SD cards with autopunch, repeat and record undo functions.Â You can also have a dedicated stereo mixdown track. As for power, just a couple AA batteries will keep this going for nearly 8 hours. Street price is right at $200 bills. TASCAM Pocketstudio product page. Continue Reading 4 Comments
These cards could help to make a particular handset or plan more attractive to a subscriber by offering songs, movies, maps for GPS (Global Positioning System) navigation or applications. However, locking the card will ensure consumers couldn’t use the content elsewhere.SanDisk reports the data lock portion could be updated remotely via IP protocols which means a vendor could update music lists, content and video depending on the subscribers requirements, needs or membership. Some critics believe this technology is coming at a bad time, since users enjoy cross platform sharing for their music, along with Apples move towards less DRM on their music.Â However, what these critics don’t see is the need to protect other types of intellectual property.Â Although music and video is the big numbers, mainstream target market, there is an infinite need in the pro-sumer and corporate world for data lock and protection.

Through an acquisition, Samsung would strengthen it’s channel for supplying it’s flash chip to retail and channel sales of end-user flash memory. With weak chip prices and fluctuating buyer habits, a move like this could strengthen Samsung’s position and would put Samsung at over 50% of world wide control of production, distribution and sales of NAND flash memory.
Avi Cohen of Avian Securities said it was an “unlikely prospect” due to SanDisk being unwilling to sell at the bottom of the cycle, and Samsung becoming a direct competitor to many of its customers and regulatory concerns. “Regulators in the US, Korea and Europe among others will likely have issue with one player controlling north of 50 per cent of NAND [Flash memory] supply,” he said.Another option is Samsung reducing it’s royalty license to SanDisk to gain synergy with the top seller, reduce SanDisk’s bottom line and secure channel distribution of flash memory.
However if a deal goes ahead, it could block efforts by Samsung rivals Toshiba and Hynix Semiconductor to topple Samsung’s market leadership. Toshiba runs joint production lines with SanDisk and Hynix is also conducting joint re-search with the US group. Samsung controls 42.3 per cent of the NAND flash memory market, trailed by Toshiba with 27.5 per cent and Hynix with 13.4 per cent, says market researcher iSuppli.Source:Â Financial Times.
