SEMICONDUCTOR INTEGRATED CIRCUIT

PROBLEM TO BE SOLVED: To cut electric current passing through a fuse element and a peripheral circuit, when making a circuit using the fuse element on a semiconductor circuit. SOLUTION: Electric current passing directly through a fuse element is cut by integrating the fuse element 33 in an inverter 52 composed of PMOS element 31 and NMOS element 32. In addition, whether the fuse is cut off or not yet is sensed by using a flip-flop circuit 35 in a subsequent stage. At this time, electric current passing through a peripheral circuit is cut by making a timing to actuate the flip-flop circuit 35 by using an inside delay circuit 34.
