Functional Description
The IDT70V9379 provides a true synchronous Dual-Port Static RAM
interface. Registered inputs provide minimal set-up and hold times on
address,data,andallcriticalcontrolinputs.Allinternalregistersareclocked
ontherisingedgeoftheclocksignal,however,theself-timedinternalwrite
pulse is independent of the LOW to HIGH transition of the clock signal.
An asynchronous output enable is provided to ease asynchronous
bus interfacing. Counter enable inputs are also provided to staff the
operationoftheaddresscountersforfastinterleavedmemoryapplications.
CE0 = VIL and CE1 = VIH for one clock cycle will power down the
internalcircuitrytoreducestaticpowerconsumption.Multiplechipenables
allow easier banking of multiple IDT70V9379's for depth expansion
configurations.WhenthePipelinedoutputmodeisenabled,twocyclesare
required with
CE0 = VIL and CE1 = VIH to re-activate the outputs.
