Notes:

1. The internal write time is defined by the overlap of

CE1

LOW, CE2 HIGH and

WE

LOW. All signals must be in valid states

to initiate a Write, but any one can go inactive to terminate the Write. The Data Input Setup and Hold timing are referenced

to the rising or falling edge of the signal that terminates the Write.

2. I/O will assume the HIGH-z state if
