Patent ID: 7093171

Claim:
A redundancy system for replacing elements of a memory array having a plurality of banks, the redundancy system comprising: a memory chip including one or more memory arrays, each of the memory arrays including a row having M banks, each of the M banks including a plurality of elements; a plurality of wordline groups, each wordline group traversing N banks of the M banks of a row of the memory array and containing a plurality of wordlines, where M>N>1 and a repair field size is selectable and is defined by M/N=2 P , where M, N, and p are positive integers; a remote fuse bay for storing at least one faulty address corresponding to a faulty element of the memory array; a fuse ray for storing fuse information corresponding to at least one bank of the memory array; and a copy logic module for copying at least one faulty address stored in the remote fuse bay into the fuse array; wherein the copy logic module is programmed to copy the at least one faulty address N times into the fuse information corresponding to a repair field of the memory array, N corresponding to the number of banks in selectable repair field.
