ABSTRACT:
A method and circuit are disclosed which can be incorporated into any circuitry which uses fused algorithms to control the circuitry. Specifically, the invention may be incorporated into an integrated circuit device by way of a circuit that controls the coupling of an input signal to an output. Careful placement of a fuse or similarly functioning element in the circuit, permits the output of said circuit to be reliably set to a desired logic state. Specifically, when the fuse element is opened, a portion of the feedback path is disconnected, thereby preventing feedback in the direction of the unwanted logic state. The present invention enables construction of a fuse circuit which latches a desired logic state with stable performance and no layout area or speed degradation.
