The storage device includes a memory device including a plurality of memory cells, a memory controller configured to control an operation performed on the memory device, and a buffer memory including a cache area and a mapping area in which mapping data indicating a mapping relationship between a logical block address and a physical block address corresponding to the operation is stored. The buffer memory allocates a portion of the mapping area to the cache area according to an allocation request received from a host, and stores data except for the mapping data in the cache area."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Host device, storage device, and method of operating the same","description":"The present technology relates to a storage device that allows access to the storage device without accessing a main memory of a host by allocating a portion of a mapping area of a buffer memory to a ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11989446","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.
