16. ALTERNATIVE CE#-CONTROLLED WRITES
NOTES:
1. Chip-Enable Controlled Writes: Write operations are driven by the valid combination of CE# and WE#. In systems where CE#
2. Sampled, not 100% tested.
3. Refer to Table 3 for valid A
4. Refer to Table 3 for valid D
5. Byte write and block erase durations are measured to completion (SR.7=1, RY/BY#=V
6. See High Speed AC Input/Output Reference Waveforms and High Speed AC Testing Load Circuits for testing characteristics.
