Data Protection
The Numonyx NAND device is designed to guarantee Data Protection during Power
Transitions.
A VDD detection circuit disables all NAND operations, if VDD is below the VLKO threshold.
In the VDD range from VLKO to the lower limit of nominal range, the WP pin should be kept
low (VIL) to guarantee hardware protection during power transitions as shown in the below
figure.
