During power-up and power-down, certain conditions must be observed. CS# must follow the voltage applied
on V

A pull-up resistor on Chip Select (CS#) typically meets proper power-up and power-down requirements.
No Write Status Register, program, or erase command should be sent to the device until V

the WEL bit is reset (0).
Each device in the host system should have the V
package pins (this capacitor is generally of the order of 0.1 µF), as a precaution to stabilizing the V

operations are disabled and the device does not respond to any commands. Note that data corruption may
result if a power-down occurs while a Write Register, program, or erase operation is in progress.
