The method includes storing a security key in a particular block in a plurality of blocks of the non-volatile memory array; utilizing, in a security logic circuit coupled to the non-volatile memory array, the security key stored in the particular block in a protocol to enable access via a port by external devices or communication networks to data stored in blocks in the plurality of blocks; and enabling read-only access to the particular block by the security logic for use in the protocol, and preventing access to the particular block via the port."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Physical unclonable function for non-volatile memory","description":"A system and method for utilizing a security key stored in non-volatile memory, and for generating a PUF-based data set on an integrated circuit including non-volatile memory cells, such as flash memo","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10469271","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.
