Abstract
A semiconductor device includes an operation unit (CPU) provided in a semiconductor chip and a temperature sensor (TS) that measures a temperature of the semiconductor chip. The semiconductor device compares a measured temperature (Ta) measured by the temperature sensor (TS) with a predetermined reference temperature (Tref). When the measured temperature (Ta) is higher than the reference temperature (Tref), the semiconductor device switches a frequency of an operation clock to be supplied to the operation unit (CPU) from a first frequency to a second frequency higher than the first frequency.
