Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 1:
2. The storage device of claim 1, wherein the oscillator is further configured when enable to discharge the charge pump, and the regulator is further configured to regulate the operating voltage by applying a pump discharge signal to selectively enable the oscillator to discharge the operating voltage,
the flag generating circuit further receives the discharge enable signal that instructs discharge of the operating voltage,
the flag generating circuit is further configured to control the flag signal in response to the busy signal and the discharge enable signal,
the busy signal transitions from the first level to the second level when the non-volatile memory device completes the operation corresponding to the operating command, and
the flag signal transitions from the first level to the second level in response to a change of the busy signal from the first level to the second level.
