Abstract
Provided is a boosting circuit which avoids a malfunction of a peripheral circuit to be connected to the boosting circuit. The boosting circuit includes: a first discharge circuit for discharging a voltage of a first output terminal when a boosting unit stops a boosting operation; and a second discharge circuit for discharging a voltage of a second output terminal. The second discharge circuit discharges the voltage of the second output terminal to a potential of the first output terminal when a difference voltage between the voltage of the second output terminal and the voltage of the first output terminal is equal to or lower than a predetermined voltage.
