In a booster circuit comprising a first pump capacitor (CP1) connected between nodes (N1, N3) and a second pump capacitor (CP2) connected between nodes (N2, N4), the booster circuit comprises first through fifth switches (S1-S5). Connected to the node (N1), the first switch (S1) is connected to one of a power-supply node, a ground node, and a booster node. Connected to the node (N2), the second switch (S2) is connected to one of the power-supply node, the ground node, and the booster node. Disposed between the nodes (N3, N4), the third switch (S3) makes or breaks. Connected to the node (N3), the fourth switch (S4) is connected to one of the power-supply node, the booster node, and a non-connective node. Connected to the node (N4), the fifth switch (N5) is connected to one of the power-supply node, the booster node, and the non-connective node.
