A semiconductor device is formed on a semiconductor wafer. The semiconductor device has: an output buffer configured to externally output an output signal received from an internal circuit; an input buffer configured to output an input signal externally received to the internal circuit; a switch configured to control electrical connection between an output terminal of the output buffer and an input terminal of the input buffer; a first transmission path provided in a scribe region of the semiconductor wafer and connecting between the output terminal and the switch; and a second transmission path provided in the scribe region and connecting between the input terminal and the switch.
