Input
Addresses Inputs: These inputs determine which cell is addressed .

WE#
Input
Write Enable: This input determines if the cycle is a READ or
WRITE cycle. WE# is LOW for a WRITE cycle and HIGH for a
READ cycle.
Chip Enable: This active LOW input is used to enable the device.
When CE# is LOW, the chip is selected. When CE# is HIGH, the
chip is disabled and automatically goes into standby power mode .
Byte Enable: These active LOW inputs allow individual bytes to be
written or read. When BLE# is LOW, the data is written to or read
from the lower byte (DQ1-DQ8). When BHE# is LOW, the data is
written to or read from the higher byte (DQ9-DQ16).
Output Enable: This active LOW input enables the output drivers .
Input/Output SRAM Data I/O: Data inputs and data outputs. Lower byte is DQ1-
DQ8 and upper byte is DQ9-DQ16.
