Abstract
Different embodiments of a one-time-programmable antifuse cell included. In one embodiment, a circuit is provided that includes an antifuse element, a high voltage device, and a sense circuit. The antifuse element has a voltage supply terminal to be at a sense voltage during sensing/reading and a higher programming voltage during programming. The sense circuit is configured to enable programming the antifuse element during programming and to sense the state of the antifuse element during sensing. The high voltage device is coupled between the antifuse element and the sense circuit to couple the antifuse element to the sense circuit during programming and sensing and to protectively shield the sense circuit from the higher programming voltage during programming.
