What is NAND Flash?

Due to the efficient architecture of NAND flash, its cell size is almost half the size of a NOR cell. This, in combination with a simpler production process, enable NAND architecture to offer higher densities, with more capacity on a given die size. As a result, NOR capacities dominate the market range from 1MB to 4MB (although 32MB is also available), while NAND capacity range is from 8MB to 512MB. This again stresses the role of NOR devices as a code storage media, while NAND devices are ideal for data storage, and are found mostly in data-rich applications.

M-Systems DiskOnChip devices are based on NAND but have a "thin controller" layer that makes integration easier (Figure 2). Data I/O has ported TrueFFS® to it's FlashCORE programmers so that M-Systems can use Data I/O most advanced programming technology
