Abstract
A boosting circuit includes a plurality of boosting circuit units, a voltage detecting circuit and a boost control circuit. The plurality of boosting circuit units have their outputs connected together and respectively having voltage boosting functions. Each of the plurality of boosting circuit units generates a boosted voltage higher than a power supply voltage in response to a drive signal. The voltage detecting circuit detects whether or not the boosted voltage is higher than a predetermined voltage, to generate a voltage control signal when it is detected that the boosted voltage is higher than a predetermined voltage. The boost control circuit limits the voltage boosting functions of predetermined ones of the plurality of boosting circuit units in response to the voltage control signal.
