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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"MLC self-RAID flash data protection scheme","description":"A two-dimensional self-RAID method of protecting page-based storage data in a MLC multiple-level-cell flash memory device.
