ABSTRACT:
A fuse download system for programming decoders for redundancy. Auxiliary fuse banks have sets of fuses that store logic states that (a) select a redundant decoder and (b) indicate the address of a faulty row/column of memory cells. When the chip is first powered up, each set of fuses is accessed and downloaded to program selected redundant decoders. Because the fuse sets can be dynamically assigned to redundant decoders on an any-for-any basis, the fault tolerance of the redundancy system is enhanced.
