High-Speed 64K x 8 Synchronous Dual-Port Static RAM
Description:
The IDT709089 is a high-speed 64K 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.
Preliminary
Industrial and Commercial Temperature Ranges
With an input data register, the IDT709089 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 IDT’s CMOS high-performance technology,
these devices typically operate on only 950mW of power.
