during a WRITE cycle, the output buffers remain in a high impedance state.
2. If the CE low transition occurs simultaneously with or later than the WE low transition in WRITE Cycle 1, the output buffers remain
in a high impedance state during this period.
3. If the CE high transition occurs simultaneously with the WE high transition, the output buffers remain in a high impedance state
during this period.
