Description

General part information

70V631 Series

The 70V631 is a high-speed 256K 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.
