DATA INTEGRITY VERIFICATION MECHANISM |
摘要 |
A method and apparatus is provided for maintaining data integrity. According to the method, a physical checksum calculation is performed on a block of data. After performing the physical checksum calculation, a logical check is performed on the data contained with the block of data. If the block of data passes the logical check, then the block of data may be written to nonvolati le memory. Thereafter, when the block of data is read from nonvolatile memory a physical checksum verification procedure is performed on the block of data t o determine whether the block of data was corrupted after performing the logic al check on the data contained with the block of data.
