| Zusammenfassung: | An external power control method includes determining whether to apply a second external voltage to a first node according to a drop of a first external voltage; generating a flag signal according to a drop of the second external voltage when the second external voltage is applied to the first node; transferring a voltage of the first node to a second node in response to the flag signal; and discharging at least one voltage of an internal circuit connected to the second node in response to the flag signal. |
