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.
