Also, because the device is disabled when RST# is asserted, it ignores its control inputs during
power-up/down. Invalid bus conditions are masked, providing a level of memory protection.
System designers should guard against spurious writes when VCC voltages are above VLKO
.
Because both WE# and CE# must be asserted for a write operation, deasserting either signal
inhibits writes to the device.
The Command User Interface (CUI) architecture provides additional protection because alteration
of memory contents can only occur after successful completion of a two-step command sequence
(see Section 3.2, “Device Commands” on page 18).
