A semiconductor device includes a pad, an internal power supply line, a pad switch including a MOS transistor to provide an electrically connectable coupling between the internal power supply line and the pad by use of a source-drain channel thereof, and a control circuit configured to control an electrical connection with respect to at least one of a gate node and a back-gate node of the MOS transistor, wherein the control circuit is configured such that at least one of the gate node and the back-gate node is electrically connectable to the pad.
