High-Speed 32K x 18 Dual-Port Synchronous Pipelined Static RAM
Industrial and Commercial Temperature Ranges

Timing Waveform of Pipelined Read-to-Write-to-Read (OE = VIL)(3)
Timing Waveform of Pipelined Read-to-Write-to-Read (OE Controlled)(3)
NOTES:
1. Transition is measured 0mV from Low or High-impedance voltage with the Output Test Load (Figure 2).
2. Output state (High, Low, or High-impedance) is determined by the previous cycle control signals.
3.
CE0, UB, LB, and ADS = VIL; CE1, CNTEN, and CNTRST = VIH. "NOP" is "No Operation".
4. Addresses do not have to be accessed sequentially since ADS = VIL constantly loads the address on the rising edge of the CLK; numbers are for
reference use only.
5. "NOP" is "No Operation." Data in memory at the selected address may be corrupted and should be re-written to guarantee data integrity.
