Abstract:
An integrated circuit for programming an electrical fuse includes a first programming device coupled to the electrical fuse for selectively providing the same with a first programming current, and a second programming device coupled to the electrical fuse for selectively providing the same with a second programming current. A detection module is coupled to the electrical fuse for generating an output indicating a resistance level of the electrical fuse, wherein the resistance level has three or more predetermined states, which are provided by selectively programming the electrical fuse with the first or second programming current.
