128K x 18 3.3V Dual-Port RAM, Interleaved I/Os

Description

The 70V639 is a high-speed 128K x 18 asynchronous dual-port static RAM designed to be used as a stand-alone dual-port RAM or as a combination Master/Slave dual-port RAM for 36-bit or more word systems. Using the Master/Slave dual-port RAM approach in 36-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic. 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.
