Description
The IDT7054 is a high-speed 4K x 8 FourPort Static RAM designed
to be used in systems where multiple access into a common RAM is
required.ThisFourPortStaticRAMoffersincreasedsystemperformance
inmultiprocessorsystemsthathaveaneedtocommunicateinrealtimeand
alsooffersaddedbenefitforhigh-speedsystemsinwhichmultipleaccess
is required in the same cycle.
The IDT7054 is also designed to be used in systems where on-chip
hardware port arbitration is not needed. This part lends itself to those
systems which cannot tolerate wait states or are designed to be able to
