SA-1100与5V英特尔StrataFlash 存储器接口

Capitalizing on two-bit-per-cell technology, IntelÒ
StrataFlash™ memory devices provide 2X the bits in
1X the space. Other benefits include more density in
less space, lowest cost-per-bit NOR devices, support
for code and data storage, and Common Flash Interface
(CFI) for easy migration to future devices.
