US Patent 7129768 Fuse circuit

A fuse circuit comprises a plurality of enable fuse units and a plurality of fuse sets. Current flows at a reset mode in the plurality of enable fuse units, and the flowing of current is controlled by enable signals outputted from the plurality of enable fuse units in the plurality of fuse sets. In the fuse circuit, a fuse set connected to the end of the enable fuse unit whose fuse is disconnected selectively performs a reset operation, thereby reducing peak current to decrease the whole current consumption.
