ADDRESS INPUTS: Inputs for addresses.
DATA INPUTS/OUTPUTS: Inputs data and commands during CUI (Command User
Interface) write cycles, outputs data during memory array, status register, query code,
identifier code reads. Data pins float to high-impedance (High Z) when the chip or
outputs are deselected. Data is internally latched during an erase or program cycle.

power-up or reset mode, the device is automatically set to read array mode. RST# must
be low during power-up/down.
OUTPUT ENABLE: Gates the device’s outputs during a read cycle.
WRITE ENABLE: Controls writes to the CUI and array blocks. Addresses and data are
latched on the rising edge of CE# or WE# (whichever goes high first).
