The present invention is directed to realize high manufacture yield and compensate variations in threshold voltage of a MOS transistor with small overhead. A semiconductor integrated circuit includes a CMOS circuit for processing an input signal in an active mode, a control switch, and a control memory. The control switch supplies a pMOS body bias voltage and an nMOS body bias voltage to an N well in a pMOS transistor and a P well in an nMOS transistor, respectively, in the CMOS circuit. The control memory stores control information indicating whether or not the pMOS body bias voltage and the nMOS body bias voltage are supplied from the control switch to the N well in the pMOS transistor and the P well in the nMOS transistor, respectively, in the CMOS circuit in the active mode.
