NOTES:
1. Chip-Enable Controlled Writes: Write operations are driven by the valid combination of CE
Y
and WE
Y
in systems where
CE
Y
defines the write pulse-width (within a longer WE
Y
timing waveform), all set-up, hold and inactive WE
Y
times
should be measured relative to the CE
Y
waveform.
2, 3, 4, 5, 6, 7, 8. Refer to AC Characteristics for WE
Y
-Controlled Write operations.
9. Read timing characteristics during write and erase operations are the same as during read-only operations. Refer to AC
Characteristics during Read Mode.
