Title: Dynamic cache correction mechanism to allow constant access to addressable index

Abstract: A technique is provided for a cache. A cache controller accesses a set in a congruence class and determines that the set contains corrupted data based on an error being found. The cache controller determines that a delete parameter for taking the set offline is met and determines that a number of currently offline sets in the congruence class is higher than an allowable offline number threshold. The cache controller determines not to take the set in which the error was found offline based on determining that the number of currently offline sets in the congruence class is higher than the allowable offline number threshold.
