When history of a request for write access and history of a request for read access to an address designated by the access request are recorded in the data memory, the controller selects a cache memory as the access destination, and otherwise, selects the main memory as the access destination."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Memory access control device, cache memory and semiconductor device","description":"A memory access control device of an embodiment includes a data memory configured to record information of an access request relating to reading and writing of data to a main memory, and a controller ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9684602","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.
