IDT7005S55PF

Product Summary

The IDT7005S55PF is a high-speed 8K x 8 Dual-Port Static RAM. The IDT7005S55PF is designed to be used as a stand-alone Dual- Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 16-bit-or-more word systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 16-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic. The IDT7005S55PF provides 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.
