Description

TheIDT709359/49isahigh-speed8/4Kx18bitsynchronousDual-

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.

the on-chip circuitry of each port to enter a very low standby power

mode. Fabricated using CMOS high-performance technology, these

devices typically operate on only 925mW of power.
