To provide a semiconductor device including a plurality of circuit blocks each of which is capable of performing power gating by setting off periods appropriate to temperatures of the respective circuit blocks. Specifically, the semiconductor device includes an arithmetic circuit, a memory circuit configured to hold data obtained by the arithmetic circuit, a power supply control switch configured to control supply of the power supply voltage to the arithmetic circuit, a temperature detection circuit configured to detect the temperature of the memory circuit and to estimate overhead from the temperature, and a controller configured to set a period during which supply of the power supply voltage is stopped in the case where a power consumption of the arithmetic circuit during the period is larger than the overhead period and to control the power supply control switch.
