摘要： A one-time programmable (OTP) cell includes an access transistor coupled to an antifuse transistor. Access transistor has a gate oxide thickness that is greater than the gate oxide thickness of the antifuse transistor so that if the antifuse transistor is programmed, the voltage felt across the gate/drain junction of the access transistor is insufficient to cause the gate oxide of the access transistor to break down. The dual gate oxide OTP cell may be used in an array in which only one OTP cell is programmed at a time. The dual gate oxide OTP cell also may be used in an array in which several OTP cells are programmed simultaneously.

摘要： 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.
