A fuse circuit includes a fuse driving unit, a separation/connection unit, a voltage equalization unit, and a latching unit. The fuse driving unit is configured to drive an output terminal in response to a fuse reset signal, depending on data programmed in a fuse. The separation/connection unit is disposed between the fuse and the output terminal and configured to separate or connect the fuse from or to the output terminal in response to a control signal. The voltage equalization unit is configured to equalize both ends of the fuse to the same voltage in response to the control signal. The latching unit is configured to latch and output the output terminal driven by the fuse driving unit.
