Patent attributes
A serial system and method for blowing antifuses are disclosed. One embodiment of antifuse system includes a plurality of latch devices connected in series from input to output. The system also includes a plurality of antifuses. The antifuses are configured to receive an output signal from a corresponding one of the latch devices. The plurality of latch devices includes a plurality of D flip-flops connected in series. Each of the D flip-flops is configured to receive an output signal from an immediately previous D flip-flop in the serial data flow and to provide an output signal to an immediately subsequent D flip-flop in the flow. In addition, the serial system provides self-detective antifuses, thus creating reliable electrical paths while saving antifuse blowing current resources and time.
