摘要：
An apparatus and method for selectively deriving Error Correction Codes (ECCs) or other data integrity information for integration into merged data blocks. First data is merged into second data that is error-protected using an ECC generated by a coding algorithm. Bytes or other data units are identified in the first data to be merged into the second data. It is determined whether each of the check bits of the ECC will differ from its original state in response to merging the first and second data. The check bits of the ECC that have been determined to differ from their respective original states are modified to create a “merged ECC.” The resulting data block includes the merged data and the merged ECC.
