A booster circuit includes a first capacitor and a second capacitor serially coupled between a first node and a second node through a third node; a third capacitor and a fourth capacitor serially coupled between a fourth node and a fifth node through a sixth node; a first switch coupling the third node with a power supply line when the fourth node is set to a first level; a second switch coupling the sixth node with the power supply line when the first node is set to the first level; a third switch transferring a plurality of electric charges of the sixth node to the second node; a fourth switch transferring a plurality of electric charges of the third node to the fifth node; a fifth switch coupling the second node with a voltage line; and a sixth switch coupling the fifth node with the voltage line.
