DESCRIPTION
Address Inputs: For memory addresses input. Addresses are internally
latched on the falling edge of WE# during a write cycle.
Chip Enable: CE# goes low activates the device's internal circuitries for
device operation. CE# goes high deselects the device and switches into
standby mode to reduce the power consumption.
Write Enable: Activate the device for write operation. WE# is active low.
Output Enable: Control the device's output buffers during a read cycle. OE#
is active low.
Data Inputs/Outputs: Input command/data during a write cycle or output data
during a read cycle. The I/O pins float to tri-state when OE# are disabled.
