Abstract

An internal power supply circuit supplies a power supply voltage to an internal circuit of a semiconductor device via an internal power supply line. The internal power supply circuit includes a reference potential generating circuit that is configured to generate a plurality of reference potentials having different temperature dependencies from each other, an internal voltage generating circuit that generates the power supply voltage with reference to a reference potential generated by the reference potential generating circuit, and a control circuit that selects a reference potential to be generated by the reference potential generating circuit.
