A charge pump includes a capacitor, a first transistor that is electrically connected between a first terminal of the first capacitor and ground, and a second transistor that is electrically connected between a second terminal of the first capacitor and an output node. During a first operation mode of the charge pump, a voltage that is boosted using the capacitor is output through the output node, and during a second operation mode of the charge pump, the first transistor and the second transistor are maintained in an ON state.
