Apparatus and methods for providing enhanced redundancy for an on-die cache

摘要

Apparatus and methods for providing enhanced redundancy for a cache are provided. For example, an on-die cache is disclosed which includes a first memory array having a defective array line; a second memory array having a defective array line; and a redundant memory array having a plurality of array lines. A first one of the array lines is mapped to the defective array line of the first array and a second one of the array lines is mapped to the defective array line of the second array.
