Description

The IDT71V35761/781 are high-speed SRAMs organized as 128K x 36/256K x 18. The IDT71V35761/781 SRAMs contain write, data, address and control registers. Internal logic allows the SRAM to generate a self-timed write based upon a decision which can be left until the end of the write cycle.
