Zusammenfassung:A request to retrieve user data stored at a memory device is received and a first error control operation associated with the user data is performed. An indication of a failure of the first error control operation is received, and in response, a subset of system data stored at the memory device is identified. A second error control operation is performed on the subset of the system data to retrieve the subset of the system data stored at the memory device, and the user data is read by using the subset of the system data retrieved based on the performing of the second error control operation.
