The memory interface is configured to receive a request to store first data in the memory device, store the first data in the memory device at a first location of the memory device, and transmit the first data and the first location to the PUF device. The PUF device is configured to create a first challenge value using the first data and the first location, generate a first response value using the first challenge value, and store the first response value as a first data integrity tag in the memory device, wherein the first data integrity tag is associated with the first data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"PUF-based data integrity","description":"A system includes a memory device configured to store data at addressable locations in the memory device, a physically unclonable function (PUF) device including an array of PUF elements, and a memory","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11531785","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.
