Abstract
A memory array having a first plurality of fuse-sharing redundant elements for replacing defective elements of the memory array. The memory array includes a first fuse, and first group of redundant elements of the first plurality of fuse-sharing redundant elements. The first group of redundant elements share the first fuse as their highest order address fuse. The memory array further includes a second group of redundant elements of the first plurality of fuse-sharing redundant elements. The second group of redundant elements is mutually exclusive with respect to the first group of redundant elements.
