Functions
To provide memory addresses.
During Sector-Erase A
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 protect the top/bottom boot block from Erase/Program operation when grounded.
To reset and return the device to Read mode.
To activate the device when CE# is low.
To gate the data output buffers.
To control the Write operations.
To provide power supply voltage: 2.7-3.6V
