By only allowing execution of operating system or other executable code after write-protecting certain portions of non-volatile memory, system security, integrity, and robustness are substantially increased."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Manufacturing mode for secure firmware using lock byte","description":"Upon initialization or startup of an electronic device, the device checks a predetermined section of non-volatile memory, referred to as the signature byte or lock byte, and allows either the manufact","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9627081","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.
