Abstract
A semiconductor device includes a clock generation unit which generates a clock signal, a first module which asserts a clock-control request signal, and one or more second modules, each of which receives the clock signal and the clock-control request signal, and asserts a clock-control acknowledge signal after stopping an operation thereof upon completion of a currently performed operation in response to the assertion of the clock-control request signal, wherein the clock generation unit selectively changes the clock signal supplied to the one or more second modules in response to assertion of all clock-control acknowledge signals output from the one or more second modules.
