Notes:
1. The internal write time is defined by the overlap of CE LOW 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 OE > VIH.
