主权项

1. An apparatus, comprising:
memory arrays including redundant groups of memory cells and non-redundant groups of memory cells; and a memory cache operatively coupled to the memory arrays, wherein the memory cache includes groups of memory cache memory cells, wherein the apparatus is operable to functionally replace a problematic one of the non-redundant groups of memory cells with one of the redundant groups of memory cells, while also being operable to functionally replace a problematic one of the groups of memory cells of the memory cache with at least two of the redundant groups of memory cells of the memory arrays, wherein replacing the problematic one of the groups of memory cells of the memory cache comprises replacing one problematic memory cell of the memory cache with at least two redundant memory cells of the memory arrays.
