What is NAND flash?
Flash memory chips are constructed of either NOR or NAND gates. Developed by Toshiba, NAND flash works like a disk rather than memory. It has faster erase and write times, higher density, and lower cost per bit than NOR flash, and ten times the endurance. However, its I/O interface allows only sequential access to data, which makes it suitable for mass-storage devices and somewhat less useful for computer memory.
