Abstract
Electronic fuse (e-fuse) systems with multiple reprogrammability are provided. In one aspect, a reprogrammable e-fuse system is provided that includes a first e-fuse string; a second e-fuse string; a selector connected to both the first e-fuse string and the second e-fuse string configured to alternately select an e-fuse from the first e-fuse string or the second e-fuse string to be programmed; and a comparator connected to both the first e-fuse string and the second e-fuse string configured to compare a voltage across the first e-fuse string to a voltage across the second e-fuse string to determine a programming state of the e-fuse system.
