Abstract

An electrical fuse device is disclosed. A circuit apparatus can include the fuse device, a first circuit element and a second circuit element. The fuse includes a first contact that has a first electromigration resistance, a second contact that has a second electromigration resistance and a metal line, which is coupled to the first contact and to the second contact, that has a third electromigration resistance that is lower than the second electromigration resistance. The first circuit element is coupled to the first contact and the second circuit element coupled to the second contact. The fuse is configured to conduct a programming current from the first contact to the second contact through the metal line. Further, the programming current causes the metal line to electromigrate away from the second contact to electrically isolate the second circuit element from the first circuit element.
