The trimming tag, therefore, can be flushed from the cache area to the non-volatile memory for non-volatile storage. The update of the host-to-device mapping table based on the trimming tag can be postponed to the moment that the controller is free."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data storage device and non-volatile memory control method","description":"Efficient space trimming of data storage device is shown, which uses a controller to program a trimming tag that corresponds to a trimming command issued by a host into a cache area of a temporary sto","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11307979","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.
