Description:
Port RAM. The memory array utilizes Dual-Port memory cells to allow
simultaneous access of any address from both ports. Registers on
control, data, and address inputs provide minimal setup and hold
times. The timing latitude provided by this approach allows systems
to be designed with very short cycle times. With an input data register, the
IDT70V3579 has been optimized for applications having unidirectional or
Pin Configuration
