Abstract:
The embodiments described herein provide antifuse devices and methods that can be utilized in a wide variety of semiconductor devices. In one embodiment a semiconductor device is provided that includes an antifuse, a first diode coupled with the antifuse in a parallel combination, and a second diode coupled in series with the parallel combination. In such an embodiment the first diode effectively provides a bypass current path that can reduce the voltage across the antifuse when other antifuses are being programmed. As such, these embodiments can provide improved ability to tolerate programming voltages without damage or impairment of reliability.
