Description

The IDT70V18 is a high-speed 64K x 9 Dual-Port Static RAM. The

IDT70V18 is designed to be used as a stand-alone 576K-bit Dual-Port

RAM or as a combination MASTER/SLAVE Dual-Port RAM for 18-bit-

or-more word system. Using the IDT MASTER/SLAVE Dual-Port RAM

approach in 18-bit or wider memory system applications results in full-

speed, error-free operation without the need for additional discrete

logic.

This device provides two independent ports with separate control,

address, and I/O pins that permit independent, asynchronous access

chip circuitry of each port to enter a very low standby power mode.

Fabricated using CMOS high-performance technology, these de-

vices typically operate on only 440mW of power.
