Abstract
A circuit includes a fuse cell, a sense circuit and an output control circuit. The fuse cell includes an electrical fuse. The sense circuit is electrically coupled to the fuse cell and configured for generating a sense signal indicative of a programmed condition of the electrical fuse, at an output of the sense circuit. The output control circuit is electrically coupled to the output of the sense circuit, and the output control circuit is configured for latching the sense signal indicative of the electrical fuse having been programmed, during a read operation of the fuse cell.
Claims21
A circuit comprising:
- a fuse cell comprising an electrical fuse;
- a sense circuit electrically coupled to the fuse cell and configured for generating a sense signal indicative of a programmed condition of the electrical fuse, at an output of the sense circuit;
- and
- an output control circuit electrically coupled to the output of the sense circuit, the output control circuit configured for latching the sense signal indicative of the electrical fuse having been programmed, during a read operation of the fuse cell.
A circuit comprising:
- a fuse cell comprising an electrical fuse;
