NOTES:

—WE#-Controlled Write Operations
for notes 1 through 10.
11. Chip-Enable controlled writes: write operations are driven by the valid combination of CE# and WE# in systems where CE#
defines the write pulse-width (within a longer WE# timing waveform), all set-up, hold and inactive WE# times should be
measured relative to the CE# waveform.
