Abstract
An electrically programmable fuse circuit, a programming method for electrically programmable fuse, and a state detection method for electrically programmable fuse are provided. The electrically programmable fuse circuit includes a plurality of fuse cells connected in series, wherein in each of the plurality of fuse cells, one terminal of the fuse cell is connected with a first programming terminal corresponding to the fuse cell, and the other terminal of the fuse cell is connected with a second programming terminal corresponding to the fuse cell via a transistor. Reliability of electrically programmable fuses may be improved.
