A fuse circuit capable of cutting off a leakage current path is provided to reduce a standby current by intercepting the leakage current path generated after a fuse is cut, thereby reducing power consumption of an electronic device. A fuse circuit includes a fuse(310), a state information output unit(350), a circuit breaker(330), and a controller(370). The fuse is connected to a first source voltage. The state information output unit outputs state information representing the connection state of the fuse in response to a first control signal. The circuit breaker disconnects the fuse from the state information output unit in response to a second control signal, whose logic level is changed according to the level change of the first control signal. The controller maintains the state information and outputs the state information as a fuse state information signal.
