Description
The 71V30 high-speed 1K x 8 dual-port static RAM is designed to be used as a stand-alone 8-bit dual-port SRAM. It has two independent ports with separate control, address, and I/O pins that permit independent, asynchronous access for reads or writes to any location in memory. An automatic power-down feature, controlled by CE, permits the on-chip circuitry of each port to enter a very low standby power mode.
