Abstract
A computer-implemented method, system, and computer program product for limiting the effects of uncorrected hard errors. A soft error is detected in the least recently used (LRU) vector. A group at the tier of the LRU vector subject to the error is then recorded. A counter tracking the number of soft errors involving the group at the tier of the LRU vector subject to the soft error is updated (e.g., increased by a value of 1). If the value of the counter exceeds a threshold value, then such a soft error is deemed to be treated as a hard error. In such a situation, an error correction process is implemented for only the affected location of the LRU vector subject to the soft error. The target way is then set to include the most recently used data item in the non-errant associated groups of the LRU vector.
