PROBLEM TO BE SOLVED: To provide a semiconductor device which can reduce capability that the existence of the blowing-out of a fuse is erroneously determined. SOLUTION: A fuse peripheral circuit has the fuse 10, a potential difference applying circuit 20, a potential difference reducing circuit 30, a terminal 40, a memory circuit 50, a transfer gate 60, and a logic gate 70. The logic gate 70 is connected to the input end of the transfer gate 60. The logic gate 70 is a transfer prevention circuit which prevents the transfer of the signal stored in the memory circuit 50 from being transmitted to the fuse 10 at the time of determining the blowing-out of the fuse 10.
