Preliminary

Description:

The IDT70T9359/49 is a high-speed 8/4K x 18 bit synchronous

Dual-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 IDT70T9359/49 has been optimized

forapplicationshavingunidirectionalorbidirectionaldataflowinbursts.An

automatic power down feature, controlled by

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

Fabricated using IDT’s CMOS high-performance technology, these

devices typically operate on only 225mW of power.
