Description
The memory array is based on Dual-Port memory cells to allow
simultaneous access from both ports. Registers on control, data, and
address inputs provide low set-up and hold times. The timing latitude
provided by this approach allow systems to be designed with very short
cycle times. With an input data register, this device has been optimized for
applications having unidirectional data flow or bi-directional data flow in
bursts.
user's option. This feature is especially useful in data communication
applications where it is necessary to use a parity bit for transmission/

reception error checking.
Dual-Ports typically operate on only 850mW of power at maximum high-
speed clock-to-data output times as fast as 12ns. An automatic power
down feature, controlled by CE, permits the on-chip circuitry of each port
to enter a very low standby power mode.
Military grade product is manufactured in compliance with the latest revision
of MIL-PRF-38535 QML, making it ideally suited for military temperature
applications demanding the highest level of performance and reliability.
