Abstract
Information technology equipment includes a circuit block, a local power source line for supplying a power source to the circuit block, a power source line, and a first transistor which is provided with a source-drain path thereof between the power source line and the local power source line, in which the first transistor is controlled to an OFF state in a first state, and is controlled to an ON state in a second state, and when the first state is shifted to the second state, the first transistor is controlled such that a rate of changing a current flowing in the source-drain path of the first transistor does not exceed a predetermined value.
