We tried to escape the iPhone buzz, but recent information came to light after some folks unscrewed the iPhone to see what’s inside. This is what flash memory they found.
The Apple iPhone flash memory is comprised of two technologies. NAND flash and NOR flash. Without knowing how Apple used these technologies we can easily conclude (without certainty) how the flash memory is being used.
Since NAND flash memory is best suited for re-write and allows an operating system to view the flash memory as a hard drive type storage space, the iPhone most likely uses NAND memory to store MP3 files, photo’s, video and other ‘come-n-go’ files.
The NOR flash memory is best suited for storing code where re-writes aren’t as frequent. NOR would be used for storing application information, such as web browser, OS, Viewer files and other ‘stable’ code which wouldn’t change too often.
It was also reveled that Samsung is supplying Apple’s iPhone with the main microprocessor chip and NAND flash memory. Intel is supplying the NOR flash memory to the iPhone.
Kicking around in technology since 2002. I like to write about technology products and ideas, but at the consumer level understanding. Some tech, but not too techie.
