ABSTRACT:
The present invention comprises a programmable structure for a integrated circuits, such as programmable read-only memory (PROM) or option selections/redundancy repair on dynamic random access memories (DRAMs), which utilizes both antifuse and fuse elements for multiple programming. Various combinations of anti-fuse and fuse elements (series or series-parallel combinations) will allow multiple programming of a given node in a particular circuit design to allow greater programming flexibility.
