Timing Waveform of Flow-Through Read-to-Write-to-Read (OE = V
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. CE
4. Addresses do not have to be accessed sequentially since ADS = V
5. "NOP" is "No Operation." Data in memory at the selected address may be corrupted and should be re-written to guarantee data integrity.
