Electrical fuse devices and methods of operating the same

摘要

Provided are an electrical fuse device and a method of operating the same. The electrical fuse device may include a fuse, and a driving element connected to the fuse and including a resistance change layer having a resistance that changes according to an applied voltage. The resistance change layer may have a metal-insulator transition (MIT) characteristic. As the driving element is turned on, a programming current may be applied to the fuse connected to the driving element.
