Abstract
There is provided a semiconductor device including: a temperature sensor detecting temperature; an inner circuit operating when supplied with a power supply voltage from a power supply line; a switch connected between the power supply line and the inner circuit; and a control circuit performing control in which, in a case where the temperature detected by the temperature sensor is higher than a threshold value, the switch is turned on when the inner circuit is in operation and the switch is turned off when the inner circuit is in non-operation, and in a case where the temperature detected by the temperature sensor is lower than the threshold value, the switch is turned on when the inner circuit is in operation and in non-operation.
