Description

The IDT7134 is a high-speed 4K x 8 Dual-Port Static RAM

designedtobeusedinsystemswhereon-chiphardwareportarbitration

is not needed. This part lends itself to those systems which cannot

tolerate wait states or are designed to be able to externally arbitrate or

withstand contention when both sides simultaneously access the

same Dual-Port RAM location.

TheIDT7134providestwoindependentportswithseparatecontrol,

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

forreadsorwritestoanylocationinmemory.Itistheuser’sresponsibility

to ensure data integrity when simultaneously accessing the same

memory location from both ports. An automatic power down feature,

controlledbyCE,permitstheon-chipcircuitryofeachporttoenteravery

low standby power mode.

FabricatedusingCMOShigh-performancetechnology,theseDual-

Ports typically operate on only 700mW of power. Low-power (LA)

versions offer battery backup data retention capability, with each port

typically consuming 200µW from a 2V battery.

The IDT7134 is packaged on either a sidebraze or plastic 48-pin

DIP, 48-pin LCC, 52-pin PLCC and 48-pin Flatpack. Military grade

product is manufactured in compliance with MIL-PRF-38535 QML,
