1. When UB and LB are in select mode (low), I/O₀ - I/O₁₅ are affected as shown. When LB only is in the select mode only
I/O₀ - IO₇ are affected as shown. When UB is in the select mode only I/O₈ - I/O₁₅ are affected as shown. If both UB and LB
are in the deselect mode (high), the chip is in a standby mode regardless of the state of CE.
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.
