MLC SELF-RAID FLASH DATA PROTECTION SCHEME |
摘要 |
A two-dimensional self-RAID method of protecting page-based storage data in a MLC multiple-level-cell flash memory device. The protection scheme includes reserving one parity sector across each data page, reserving one parity page as the column parity, selecting a specific number of pages to form a parity group, writing into the parity page a group parity value for data stored in the pages of the parity group. The parity sector represents applying a RAID technique in a first dimension. The group parity represents applying a RAID technique in a second dimension. Data protection is achieved because a corrupted data sector can likely be recovered by the two dimensional RAID data. |
