A semiconductor device adopts an exclusive control unit that exclusively controls communication performed by a communication unit capable of communicating with the outside and access to a predetermined storage unit. For example, the communication status of the communication unit is determined based on whether a communication clock is active or inactive, and the exclusive control is exercised based on the determination result."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device and access restriction method","description":"The present invention prevents unauthorized functions from being installed to a predetermined storage unit in the background through a communication function that is being used for authorized communic","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9697364","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.
