Abstract:
A method for programming a multi-level electrical fuse system comprises providing a fuse box with an electrical fuse and providing one of at least two fuse writing voltages to the electrical fuse to program the electrical fuse to one of at least two resistance states. The fuse box comprises at least one electrical fuse, a programming device serially coupled to the electrical fuse, and a variable power supply coupled to the fuse box and configured to generate two or more voltage levels.
