Abstract
A method and structure for blowing a fuse including removing an insulator above a fuse link and etching the fuse link.
Claims20
A programming device comprising:
- an inductive circuit in which an inductance is alterable,
- wherein said inductive circuit includes a primary turn, a secondary turn, and
- wherein said programming device comprises a fuse and said shorted turn comprises a fuse link.
A fuse comprising:
- a primary turn;
- a secondary turn above said primary turn;
- and
- a shorted turn above said secondary turn,
- wherein removing a portion of said shorted turn changes an inductance of said fuse.
2 more elements
A programming device comprising:
- an inductive circuit,
- wherein said inductive circuit includes a primary turn, a secondary turn and a shorted turn, and
- wherein said shorted turn comprises a fuse link adapted to alter an inductance of said inductive circuit.
The programming device in cliam 15, wherein removing a portion of said shorted turn changes said inductance.
The programming device in clain 15, wherein said shorted turn is isolated from other circuitry.
