Micron NAND Flash devices include an asynchronous data interface for high-performance 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
asynchronous data interface: CE#, CLE, ALE, WE#, and RE#. Additional signals control
hardware write protection (WP#) and monitor device status (R/B#).
