Waveform of Write Cycle No.1 (R/W Controlled Timing)
Random Access Port
Waveform of Write Cycle No.2 (CE, LB, and/or UB Controlled Timing)
Random Access Port
NOTES:
1. R/W, CE, or LB and UB must be inactive during all address transitions.
2. A write occurs during the overlap of R/W = V
3. t
4. During this period, I/O pins are in the output state and the input signals must not be applied.
5. If the CE LOW transition occurs simultaneously with or after the R/W LOW transition, the outputs remain in the High-impedance state.
6. OE is continuously HIGH, OE = V
7. I/O
8. CMD access follows the standard CE access described above. If CMD = V
