... High-Speed 36K ( Synchronous Dual-Port Static RAM Description The IDT70914 is a high-speed bit synchronous Dual-Port RAM. The memory array is based on Dual-Port memory cells to allow simultaneous access from both ports. Registers on control, data, and address inputs provide low set-up and hold times. The timing latitude provided by this approach allow systems to be designed with very short cycle times ...
