Description

TheIDT7052isahigh-speed2Kx8FourPort™StaticRAMdesigned

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 IDT7052 is also designed to be used in systems where on-chip

hardware port arbitration is not needed. This part lends itself to those
