Abstract
A reprogrammable fuse has a pair of non-volatile memory cells differentially programmed. The pair of non-volatile memory cells are connected to a pair of bitlines and through a pair of switches to a precharging voltage. The switches are controlled by a precharging and equalization signal, which when activated, serves to precharge the bitlines. The charged bitlines are then connected to the pair of differentially programmed non-volatile memory cells and one of the bitlines is discharged faster than the other. The resultant output is taken from one of the bitlines.
