摘要
An apparatus comprises a non-associative memory comprising a plurality of storage locations, and error recovery storage to store at least one error recovery entry providing a recovery value for a corresponding storage location of the non-associative memory. Control circuitry is responsive to a non-associative memory read request specifying a target address of a storage location of the non-associative memory, when the error recovery storage includes a valid matching error recovery entry for which the corresponding storage location is the storage location identified by the target address, to return the recovery value stored in the valid matching error recovery entry as a response to the non-associative memory read request, instead of information stored in the storage location identified by the target address. This enables the apparatus to continue to function even if hard errors occur in a storage location of the non-associative memory.
