ABSTRACT:
A one-time programmable circuit uses forced BJT hFEdegradation to permanently store digital information as a logic zero or logic one state. The forced degradation is accomplished by applying a voltage or current to the BJT for a specific time to the reversed biased base-emitter junction, allowing a significant degradation of the junction without destroying it.
