A semiconductor integrated circuit includes a first circuit, a second circuit and a control circuit. The first circuit is configured by a first MOS transistor, and a threshold voltage of the first MOS transistor is a first threshold voltage. The second circuit has same logic as the first circuit, and is configured by a second MOS transistor. A threshold voltage of the second MOS transistor is a second threshold voltage, and the second threshold voltage is lower than the first threshold voltage. The control circuit makes one of the first circuit and the second circuit operate depending on a temperature of a chip. The first circuit and the second circuit are installed in a chip.
