Flash NAND memory
is striving for ubiquity. It is making appearances now in the form of
USB drives (a portable 256 MB portable dongle that fits in your shirt
pocket) and Flash cards for cameras, MP3 players, and cell phones, to
name a few. The heir apparent to Flash NOR, NAND is currently 62x faster
to erase and 17x faster to write than NOR. It uses 200x less power to
erase and 60x less power to write. By stacking 4 die, the density is
4x greater than NOR, and the scalability (not applicable to NOR) promises
much higher densities soon. Look for flash NAND to replace hard drives
(no moving parts!) in notebook computers in the next 2 years, where
battery life will be extended 3-4x. It's about time.
