Description

The IDT709279/69 is a high-speed 32/16K x 16 bit synchronous

Dual-Port RAM. The memory array utilizes Dual-Port memory cells to

allowsimultaneousaccessofanyaddressfrombothports.Registerson

control,data,andaddressinputsprovideminimalsetupandholdtimes.

The timing latitude provided by this approach allows systems to be

designed with very short cycle times.

Pin Configurations(2,3,4)

Withaninputdataregister,theIDT709279/69hasbeenoptimizedfor

applicationshavingunidirectionalorbidirectionaldataflowinbursts.An

automatic power down feature, controlled by CE0and CE1, permits the

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

Fabricated using CMOS high-performance technology, these devices

typically operate on only 950mW of power.
