Abstract
A semiconductor integrated circuit is provided which includes a charge pump circuit for forming a step-up (boost) voltage higher than a desired internal voltage, a voltage dividing circuit which forms a plurality of divided voltages based on a reference voltage, and a control circuit which intermittently operates the charge pump circuit so that an output voltage of the charge pump circuit provides the desired internal voltage obtained by adding a voltage obtained by multiplying a particular voltage among the plurality of divided voltages by n to a predetermined divided voltage.
