Abstract
A semiconductor device includes an electric fuse circuit and a program protective circuit. The electric fuse circuit includes a fuse element and a transistor connected together in series and placed between a program power supply and a grounding, and controlling sections. The program protective circuit is placed in parallel with the electric fuse circuit and between the program power supply and the grounding. When a surge voltage is applied between the program power supply and the grounding, the foregoing structure allows a part of a surge electric current can flow through the program protective circuit.
