When a read request is made from the host interface circuit to the data buffer circuit, the data buffer circuit returns read data stored in the buffer memory upon confirming that the tag information stored in the first register and the tag information stored in the second register match each other."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Memory controller, memory system, and control method of memory system","description":"A memory controller includes a host interface circuit connectable to a host device by a bus conforming to a memory card system specification, a data buffer circuit including a buffer memory, a tag inf","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11520719","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.
