1. A reprogrammable electrically programmable fuse (eFuse), comprising: a first eFuse coupled to a first programming current source and a first sensing current source; a second eFuse coupled to a second programming current source and a second sensing current source; control logic that controls application of a first programming current from the first programming current source and a first sensing current from the first sensing current source to the first eFuse, and that controls application of a second programming current from the second programming current source and a second sensing current from the second sensing current source to the second eFuse; and a sensing amplifier, coupled to the first eFuse and second eFuse, which senses a difference in signal output of the first eFuse and signal output of the second eFuse.
