Abstract
A semiconductor integrated circuit includes a logic circuit having a plurality of operation modes, a power source circuit that generates a power source voltage to be supplied to the logic circuit, a power source wiring that couples the power source circuit and the logic circuit, and a charge control block that holds charges for controlling the voltage of the power source wiring. The power source circuit generates a first power source voltage for causing the logic circuit to operate in a computing mode and a second power source voltage for causing the logic circuit to operate in a sleep mode. The charge control block includes a capacitor, a first switch, and a voltage supply unit that supplies the second power source voltage or a third power source voltage lower than the second power source voltage, to the capacitor.
