2. When the device is in standby mode, control inputs (WE, OE, UB, and LB), address inputs and data input/outputs are internally
isolated from any external influence and disabled from exerting any influence externally.
3. When WE is invoked, the OE input is internally disabled and has no effect on the circuit.
4. The device will consume active power in this mode whenever addresses are changed. Data inputs are internally isolated from
any expernal influence.
