To provide memory address. During Sector-Erase AMS-A11 address
lines will select the sector. During Block-Erase AMS-A15 address lines will
select the block.
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 active 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
