Each group of pages in the respective block includes an assigned parity page, and each page of the respective block has a plurality of sectors, including an assigned parity sector. The storage device is operable to program and erase data on a page at a predetermined speed, and detect an error rate for each page of a block and identify a group of high error pages based on the error rates. Further, the storage device is configured to apply a speed slower than the predetermined speed in programming and erasing data on the identified high error pages."},"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":"In a multiple level cell flash memory data storage device, a flash memory array has a plurality of blocks, where each block is an erase unit and has a plurality of pages, and a respective block includ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8484534","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
