Abstract
A semiconductor device includes a first clock control circuit for controlling a first clock source; a second clock control circuit for sending a first clock request to the first clock control circuit in response to a block clock request from an intellectual property (IP) block, and controlling a second clock source, which receives a clock signal from the first clock source, to generate a stopped clock signal, which is a clock signal turned off for a predetermined amount of time; and a driver circuit for receiving a block control signal, and outputting the block control signal to the IP block while the short stopped clock signal is output to the IP block.
