70T653M - Block Diagram
Description
The 70T653M is a high-speed 256K x 36 asynchronous dual-port static RAM designed to be used as a stand-alone 18874K-bit dual-port RAM. An automatic power-down feature controlled by the Chip Enables (either CE0 or CE1) permits the on-chip circuitry of each port to enter a very low standby power mode.
