Abstract: Uncorrectable (UNC) marking on a non-volatile memory is provided. In response to a UNC marking command issued by a host, a cyclic redundancy check (CRC) engine provides a specific CRC code to mark a logical address segment as uncorrectable, wherein the logical address segment is requested to be marked as uncorrectable by the UNC marking command. As long as the specific CRC code is recognized, a CRC procedure is not required and the data requested by the host is directly determined as uncorrectable.
