Abstract
In one embodiment, a cache element allocation method is provided. Each cache element on a CPU is assigned a quality rank based on the error rate of the cache element. If an allocated cache element is deemed to be faulty, the quality rank of the faulty allocated cache element is compared with the quality rank of the non-allocated cache elements. If a non-allocated cache element has a lower quality rank than the allocated cache element, the non-allocated cache element is swapped in for the allocated cache element.
