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.
Output Enable: This active LOW input enables the output drivers .
