Abstract: A fuse circuit includes a plurality of fuses, a plurality of switches and a plurality of trimming components. The fuses are coupled in parallel to a first node and a second node. The first node is coupled to an operating voltage. The switches are coupled to the second node. The trimming components are respectively disposed between the switches and a ground voltage, and coupled to the second node via the switches, respectively. When one of the trimming components is activated, the activated trimming component allows a plurality of branch currents to be generated between the first node and the second node. The branch currents respectively flow through the fuses so that one of the fuses is blown out by the branch current flowing through the one of the fuses.
