Abstract
A semiconductor device includes a control circuit configured to suppress a current variation by turning on or off a constant current source when transitioning to a standby mode. The control circuit has a function of predicting a current variation value from register information and information of current profile. The control circuit has a function of optimizing single control amount of the current source and the number of times of control of the current source based on the predicted current variation value.
