The microcontroller maintains a plurality of logical-to-physical address mapping tables and a link table on the flash memory to record mapping information between the host and the flash memory and records a link table indicator on the flash memory to indicate a position of the link table. The link table indicates positions of the plurality of logical-to-physical address mapping tables, and each entry in the link table corresponds to one logical-to-physical address mapping table. Further, the microcontroller erases user of logical addresses corresponding to N logical-to-physical address mapping tables."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data storage device and flash memory control method","description":"The data storage device included a flash memory, divided into a plurality of blocks with each block comprising a plurality of physical pages, and a control unit, coupling the flash memory to a host an","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9842030","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.
