The stabilized security key is moved from the set of nonvolatile memory cells to a cache memory, and utilized as stored in the cache memory in a security protocol. Also, data transfer from the PUF circuit to the set of nonvolatile memory cells can be disabled after using the PUF circuit to produce the security key, at a safe time, such as after the security key has been moved from the set of nonvolatile memory cells to the cache memory."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Stable physically unclonable function","description":"A system and method use a physical unclonable function in a PUF circuit on an integrated circuit to generate a security key, and stabilize the security key by storage in a set of nonvolatile memory ce","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11258599","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.
