Preliminary
Description:
The IDT70V9169/59 is a high-speed 16/8K x 9 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 IDT70V9169/59 has been optimized
for applications having unidirectional or bidirectional data flow in bursts. An
automatic power down feature, controlled by
CE
0
and CE
1,
permits the
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 450mW of power.
