Functions
To provide memory addresses. During Sector-Erase A
sector. During Block-Erase A
To output data during Read cycles and receive input data during Write cycles.
Data is internally latched during a Write cycle.
The outputs are in tri-state when OE# or CE# is high.
To activate the device when CE# is low.
To gate the data output buffers.
To control the Write operations.
To provide power supply voltage:
Unconnected pins.
