Timing Waveform of Pipelined Read-to-Write-to-Read
(OE = V
NOTES:
1. Output state (High, Low, or High-impedance) is determined by the previous cycle control signals.
2. CE
3. Addresses do not have to be accessed sequentially since ADS = V
4. "NOP" is "No Operation." Data in memory at the selected address may be corrupted and should be re-written to guarantee data integrity.
Timing Waveform of Pipelined Read-to-Write-to-Read ( OE Controlled)
NOTES:
1. Output state (High, Low, or High-impedance) is determined by the previous cycle control signals.
2. CE
3. Addresses do not have to be accessed sequentially since ADS = V
4. This timing does not meet requirements for fastest speed grade. This waveform indicates how logically it could be done if timing so allows.
