AC CHARACTERISTICS Write Erase Program Operations
NOTES
1 Read timing characteristics during read write operations are the same as during read-only operations Refer to AC Char-
acteristics for Read-Only Operations
2 Chip-Enable Controlled Writes Write operations are driven by the valid combination of Chip-Enable and Write-Enable In
systems where Chip-Enable defines the write pulse width (within a longer Write-Enable timing waveform) all set-up hold and
inactive Write-Enable times should be measured relative to the Chip-Enable waveform
