Abstract
Methods and apparatus defer correction of an error in a tag entry of a cache tag array. An address of requested data, including an address tag field, can be received by a cache. A first hit indication based at least in part on a comparison of the address tag field and a first tag entry can be generated and result in outputting of a first data entry of a data array. An error in the tag entry can be detected, and the first data entry can be disregard based at least in part on the detected error.
