Abstract: A semiconductor device includes a regulator circuit, a charge pump circuit, and a control circuit. The regulator circuit is configured to regulate a voltage input from outside and output a regulated voltage. The charge pump circuit is configured to receive the regulated voltage as an input voltage, boost the input voltage, and output a boosted voltage. The control circuit is configured to cause the regulator circuit to vary a voltage level of the regulated voltage based on voltage value information about the voltage input from the outside.
