Low voltage efuse programming circuit and method
Abstract:
A circuit for programming a fuse is disclosed. The circuit includes a voltage supply terminal (Vf) and a semiconductor controlled rectifier (222, 224). The fuse is coupled between the voltage supply terminal and the semiconductor controlled rectifier. A switching circuit (200, 202, 208, 210) is coupled to the semiconductor controlled rectifier.
