N02L63W3A
Functional Block Diagram
Functional Description
1. When UB and LB are in select mode (low), I/O
2. When the device is in standby mode, control inputs (WE, OE, UB, and LB), address inputs and data input/outputs are internally
3. When WE is invoked, the OE input is internally disabled and has no effect on the circuit.
