709099L
High-Speed 128K x 8 Synchronous Pipelined Dual-Port Static RAM
Industrial and Commercial Temperature Ranges
Description
The IDT709099 is a high-speed 128K x 8 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 IDT709099 has been optimized for
applications having unidirectional or bidirectional data flow in bursts.
An automatic power down feature, controlled by CE0 and CE1, permits
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 1.2W of power.
