IDT70914S15PF

DESCRIPTION:

The IDT7099 is a high-speed 4K x 9 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 realized cycle times. With an input data register, this device has been optimized for applications having unidirectional data flow or bi-directional data flow in bursts. Changing data direction from reading to writing normally requires one dead cycle.
