ABSTRACT:
A electrically blowable fuse is programmed using an electro-migration effect and is reprogrammed using a reverse electro-migration effect. The state (i.e., “opened” or “closed”) of the electrically blowable fuse is determined by a sensing system which compares a resistance of the electrically blowable fuse to a reference resistance.
