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.

◆

True FourPort memory cells which allow simultaneous

access of the same memory locations

◆

Fully asynchronous operation from each of the four ports:

P1, P2, P3, P4

◆

Versatile control for write-inhibit: separate BUSY input to

TheIDT7052isalsodesignedtobeusedinsystemswhereon-chip

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

control write-inhibit for each of the four ports
