WRITE CYCLE NO. 4
Notes:
1. The internal Write time is defined by the overlap of CE = LOW, UB and/or LB = LOW, and WE = LOW. All signals must be
2. Tested with OE HIGH for a minimum of 4 ns before WE = LOW to place the I/O in a HIGH-Z state.
3. WE may be held LOW across many address cycles and the LB, UB pins can be used to control the Write function.
in valid states to initiate a Write, but any can be deasserted to terminate the Write. The t
referenced to the rising or falling edge of the signal that terminates the Write.
