ABSTRACT:
A programmable antifuse circuit to cancel a previously enabled redundant element repair is described. The programmable antifuse circuit is used for memory integrated circuits having redundant memory elements. Once a redundant memory element is employed, if a defect is found with respect to that element after the memory integrated circuit is repaired, the programmable antifuse circuit is employed to disable the redundant element repair. As described, the programmable antifuse circuit may be used with a variety of memory integrated circuits.
