Abstract
The embodiments of methods and structures disclosed herein provide mechanisms of forming and programming a metal-via fuse. The metal-via fuse and a programming transistor form a one-time programmable (OTP) memory cell. The metal-via fuse has a high resistance and can be programmed with a low programming voltage, which expands the programming window.
