ABSTRACT:
According to embodiments of the present invention, an antifuse circuit is operated by coupling an elevated voltage to a first terminal of an antifuse, controlling current in the antifuse with a program driver circuit coupled to a second terminal of the antifuse, and shunting current around the antifuse with a bypass circuit coupled between the first terminal of the antifuse and the program driver circuit to protect the antifuse. The antifuse includes a layer of gate dielectric between the first terminal and the second terminal. The embodiments of the present invention protect a gate dielectric antifuse.
