Using ECC Data for Write Deduplication Processing |
| 摘要 |
Method and apparatus for managing data in a memory. In accordance with some embodiments, a first data object and an associated first ECC data set are generated and stored in a non-volatile (NV) main memory responsive to a first set of data blocks having a selected logical address. A second data object and an associated second ECC data set are generated responsive to receipt of a second set of data blocks having the selected logical address. The second data object and the second ECC data set are subsequently stored in the in the NV main memory responsive to a mismatch between the first ECC data set and the second ECC data set. |

1. A method comprising:
generating and storing a first data object and an associated first ECC data set in a non-volatile (NV) memory responsive to a first set of data blocks with a selected logical address; generating a second data object and an associated second ECC data set responsive to receipt of a second set of data blocks having the selected logical address; and storing the second data object and the second ECC data set in the NV main memory responsive to a mismatch between the first ECC data set and the second ECC data set. |
