ABSTRACT:
A plurality of diode-connected MOS transistors are arranged in cascade connection, and clocks are supplied to nodes between the MOS transistors. A node (N40) is connected to a first voltage source line (VCC) via a first switch (SW1), a node (N46) is connected to a second voltage source (GND) via a second switch (SW2), an intermediate node (N43) is connected to a third voltage source (VCC) via a third switch (SW3). The third switch is turned ON and the first and second switches are turned OFF to output the positive high voltage (VPP) from the node (N46) and also to output the negative high voltage (VBB) from the node (N40).
