Address Buffer & Latches
Control Logic
To provide memory addresses. During sector erase A19~A11 address
lines will select the sector. During block erase A19~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 activate the device when /CE is low.
To gate the data output buffers.
To control the write operations.
To provide 3-volt supply ( 2.7V-3.6V ).
