High-Speed 36K (4K x 9) Synchronous Dual-Port Static RAM
Commercial Temperature Range
Description
user's option. This feature is especially useful in data communication
applications where it is necessary to use a parity bit for transmission/
receptionerrorchecking.
The IDT70914 is a high-speed 4K x 9 bit synchronous Dual-Port
RAM. 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
providedbythisapproachallowsystemstobedesignedwithveryshort
cycletimes.Withaninputdataregister,thisdevicehasbeenoptimizedfor
applicationshavingunidirectionaldatafloworbidirectionaldataflowin
bursts.
FabricatedusingCMOShigh-performancetechnology,these Dual-
Ports typicallyoperateononly850mWofpoweratmaximumhigh-speed
clock-to-dataoutput times as fast as12ns.An automaticpowerdown
feature, controlled by CE, permits the on-chip circuitry of each port to
enter a very low standby power mode.
The IDT70914 ispackaged ina68-pinPLCC,andan80-pinTQFP.

NOTES:
1. For tCYC = min.; data out coincident with the rising edge of the subsequent write clock can occur. To ensure writing to the correct address location, the write must
be repeated on the second write clock rising edge. If CE = VIL, invalid data will be written into array. The An+1 must be rewritten on the following cycle.
2. OE LOW throughout.
3. Transition is measured 0mV from Low or High-impedance voltage with the Output Test Load (Figure 2).
4. For tCYC > min.; OE may be used to avoid data out coincident with the rising edge of the subsequent write clock. Use of OE will eliminate the need for the write to
be repeated.
