128K x 36, 256K x 18 memory configurations

The IDT71V35761/781 are high-speed SRAMs organized as

128Kx36/256Kx18.TheIDT71V35761/781SRAMscontainwrite,data,

Supports high system speed:

Commercial:

– 200MHz 3.1ns clock access time

CommercialandIndustrial:

– 183MHz 3.3ns clock access time

– 166MHz 3.5ns clock access time
