摘要
One or more selected fuses among a plurality of fuses are blown by using electronic means to discharge a capacitor and route the resulting current spike to the selected fuse. Also, a driver output current is approximated by measuring suply currents for an unloaded output and for a loaded output and comparing the two supply currents. If the driver output is connected to the active end of a fuse, the supply current demanded by the driver indicates a state of the fuse. The invention finds particular utility when used on an integrated circuit memory array with fuse activated redundancy.
