ABSTRACT:
A voltage generation circuit has a charge pump circuit, a clamping circuit for clamping an output voltage of the charge pump circuit, and detecting means for detecting the output voltage of the charge pump circuit and supplying a control signal for boosting the output voltage to the charge pump circuit when the detected output voltage is lower than a reference voltage, wherein the detecting means includes a circuit for stopping supply of a control signal. This circuit stops supply of the control signal to the charge pump circuit when the clamping circuit is in operation.
