A semiconductor integrated circuit includes a fuse connected between a first node and a second node, a first driver configured to pull down a voltage of the first node in an initialization period in response to a fuse sensing signal, a second driver configured to pull up a voltage of the second node in an initial period of a fuse sensing period in response to the fuse sensing signal, a sensor configured to determine whether the fuse is blown or not in response to a voltage of the first node, and a third driver configured to drive the second node to a voltage level lower than a pull-up voltage level of the second driver after the initial period of the fuse sensing period in response to an output signal of the sensor and the fuse sensing signal.
