General Description
Micron NAND Flash devices include an asynchronous data interface for high-performance I/O operations. These devices use a highly multiplexed 8-bit bus (I/Ox) 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 and monitor device status (R/B#).
This hardware interface creates a low pin-count device with a standard pinout that remains the same from one density to another, enabling future upgrades to higher densities with no board redesign.
A target is the unit of memory accessed by a chip enable signal. A target contains one or
more NAND Flash die. A NAND Flash die is the minimum unit that can independently
execute commands and report status. A NAND Flash die, in the ONFI specification, is
referred to as a logical unit (LUN). There is at least one NAND Flash die per chip enable
signal. For further details, see Device and Array Organization.
This device has an internal 4-bit ECC enabled. See Internal ECC and Spare Area Mapping for ECC for more information.
