ABSTRACT:
A pump circuit includes first and second transistors connected between an input terminal and an output terminal, and a capacitor which is connected at its one end to the connection node of the first and second transistors. The pump circuit is responsive to control signals applied to the gate electrodes of the first and second transistors and another end of the capacitor to output from the output terminal a second voltage which is approximately equal to a first voltage applied to the input terminal. A back-gate voltage generating circuit which produces a third voltage which is less than the lower one of the first and second voltages. The third voltage is applied to at least the back gate of the second transistor which outputs the second voltage.
