A semiconductor device includes a first circuit, a second circuit, and a first voltage dividing circuit. The first circuit is coupled to a first terminal. The first circuit is operable by a first voltage supplied from the first terminal. The second circuit is coupled through a first resistive element to the first terminal. The second circuit is operable by a second voltage supplied through the first resistive element from the first terminal. The second voltage is smaller in absolute value than the first voltage. The first voltage dividing circuit is coupled to a first node between the first resistive element and the second circuit. The first voltage dividing circuit has a conductive state and a non-conductive state. The first voltage dividing circuit is kept in the conductive state while applying the first voltage to the first terminal to allow the first circuit to operate by the first voltage. |
