Abstract
In an SOI-type semiconductor device, a power supply voltage is applied to back gates of P-channel MOS transistors in a standby mode, and a voltage lower than the power supply voltage is applied to the back gates of the P-channel MOS transistors in an active mode. A ground voltage is applied to back gates of N-channel MOS transistors in the standby mode, and a voltage higher than the ground voltage is applied to the back gates of the N-channel MOS transistors in an active mode.
