DESCRIPTION
Address Inputs: For memory addresses and command register.
Addresses are internally latched during a write cycle.
Chip Enable: CE# low activates the device's internal circuitries
for device operation. CE# high deselects the device and
switches into standby mode to reduce the power consumption.
Please refer to DC characteristics table.
Write Enable: Activate the device for write operation. WE# is
active low.
Output Enable: Control the device's data buffers during a read
cycle. OE# is active low.
Data Inputs/Outputs: Inputs array data during program operation,
when CE# and WE# are active. Data is internally latched during
the write and program cycles. When CE# and OE# are active,
the output sends array data, manufacturer code or device code.
The data pins float to tri-state when the chip is deselected or the
outputs are disabled.
