A semiconductor device contains a semiconductor chip, and includes first and second circuits, a control signal line and a terminal. The first circuit is arranged in a center of the semiconductor chip and is configured to operate at a first voltage. The second circuit is arranged in an input/output circuit area around the first circuit on the semiconductor chip, and is configured to operate at the first voltage and a second voltage and to transfer a signal between an external unit outside the semiconductor chip and the first circuit. The control signal line is provided for the input/output circuit area on the semiconductor chip. The terminal is connected with the control signal line and supplied with a control signal. The second circuit stops a transfer of the signal between the external unit and the first circuit in response to the control signal which is transferred on the control signal line.
