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.
Timing Waveform of Pipelined Read with Address Counter Advance
NOTES:
1. CE
2. If there is no address change via ADS = V
