Beschreibung
Zusammenfassung:	A booster comprises first to fourth boosting circuits which receive first to fourth signals and provide first to fourth boosted potentials to first to fourth nodes, respectively; a first precharge circuit which is controlled by the fourth boosted potential of the fourth node in order to precharge a first node; a second precharge circuit which is controlled by the second boosted potential of the second node and precharges the third node; and a first output circuit which outputs the boosted potential to the first node. Since there is no voltage drop in each of the boosted potentials of the second and fourth nodes, it is possible to create a high potential difference in the first and third precharge circuits, and to output a specific boosted potential without lowering the speed at which the first and third nodes are precharged.
