  • Programmable efuse and sense circuit
    Patent number: 7902903
    Abstract: A circuit for electric fuses includes circuits for sensing status and programming that have separate paths for each operation. The circuit includes a plurality of electrically programmable fuses and, associated with each fuse, a switch for coupling a first terminal of the fuse to a ground supply for programming or to a comparator for sensing. The circuit uses a switched current source to supply current to the fuses for programming. The comparator senses a fuse status when a current source is switched through the fuse. The comparator compares a voltage across the fuse and associated switches to a comparison voltage across a comparison resistor and switches included for matching.
