摘要： A control circuit controls a power-source-voltage feed circuit, and controls a power source voltage fed to a target circuit. A reference-speed monitor monitors whether or not a delay time of a critical path in the target circuit is satisfies a required operational speed. A voltage-difference monitor monitors a difference between the power source voltage of the target circuit and a threshold voltage of the target circuit, to output the voltage difference information. The control circuit determines whether to increase or decrease the power source voltage based on a result of monitoring by the reference-speed monitor. The control circuit determines the change rate of the power source voltage so that the control rate of the power source voltage is proportional to the voltage difference information output from the voltage-difference monitor.

摘要： A dynamic semiconductor device is provided with a plurality of master step sections having hatch sections for temporarily storing input data and dynamic gate sections; a plurality of slave step sections, which are alternately connected with master step sections and provided with dynamic gate sections or with latch sections and dynamic gate sections; and a timing signal generating section for generating a signal for controlling operation of the master step sections and the slave step sections. The timing signal generating section supplies the latch sections with signals for storing data of the previous step before the data is erased.
