General Description

Micron NAND Flash devices include an asynchronous data interface for high-perform ance I/O operations. These devices use a highly multiplexed 8-bit bus (DQx) to transfer commands,address, and data. There are five control signals used to implement the asyn chronous data interface: CE#, CLE, ALE, WE#, and RE#. Additional signals control hardware write protection (WP#) and monitor device status (R/B#).
