Provided is a semiconductor device including a plurality of fuse circuits. Each of the fuse circuits includes: a first signal generator generating a first signal to a first node in response to a power-up signal; a pull-down transistor pulling down a second node in response to the first signal; a pull-up transistor and a fuse which are connected in series between a power supply voltage and the second node and pulling up the second node in response to the first signal when the fuse is not cut; a buffer buffering a signal output from the second node and generating a control signal; and a standby reset transistor resetting the second node in response to the control signal output from the buffer, wherein the pull-down transistor and the standby reset transistor have threshold voltages lower than a threshold voltage of the buffer. Also, each of the fuse circuits further includes an active reset transistor resetting the second node in the active mode in response to the reset control signal. Accordingly, the semiconductor device can reduce an undesired leakage current when the fuse is not cut, and also prevent change in the state of the control signal when the fuse is cut.
