    摘要: Some embodiments provide a memory cell comprising a body region doped with charge carriers of a first type, a source region disposed in the body region and doped with charge carriers of a second type, and a drain region disposed in the body region and doped with charge carriers of the second type. According to some embodiments, the body region, the source region, and the drain region are oriented in a first direction, the body region and the source region form a first junction, and the body region and the drain region form a second junction. Moreover, a conductivity of the first junction from the body region to the source region in a case that the first junction is unbiased is substantially less than a conductivity of the second junction from the body region to the drain region in a case that the second junction is unbiased. Some embodiments further include a transistor oriented in a second direction, wherein the second direction is not parallel to the first direction.

    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.
