<p>A MOS circuit in which a channel leakage current decreasing in inverse proportion to a substrate bias voltage and a junction leakage current increasing in proportion to the substrate bias voltage occur has an active mode in which the MOS circuit carries out a desired circuit operation and a standby mode in which the MOS circuit stops the circuit operation. A substrate bias circuit generates a substrate bias voltage and supplies it to the MOS circuit so that the region may be one where the total leakage current of the channel leakage current and the junction leakage current is a minimum in the standby mode.</p> |
