In one embodiment, a semiconductor integrated circuit is provided a first well region, a second well region, a first body bias supply unit and a second body bias supply unit. The first well region includes a first transistor having a first threshold voltage. The second well region includes a second transistor having an absolute value of a second threshold voltage higher than an absolute value of the first threshold voltage. The second well region is separated from the first well region. The second well region has the same conductive type as the first well region. The first body bias supply unit supplies a first body bias voltage to the first well region. The second body bias supply unit supplies a second body bias voltage to the second well region.
