The forming pulse has a forming pulse level characterized by inducing a change in resistance in a first subset of the set from an initial resistance range to an intermediate resistance range, while after the forming pulse a second subset of the set has a resistance outside the intermediate range. The method includes applying a programming pulse to the first and second subsets. The programming pulse has a programming pulse level characterized by inducing a change in resistance of the first subset from the intermediate range to a first final range, while after the programming pulse the second subset has a resistance in a second final range, whereby the first and second subsets store said data set."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Chip ID generation using physical unclonable function","description":"A method for generating a data set on an integrated circuit including programmable resistance memory cells includes applying a forming pulse to all members of a set of the programmable resistance memo","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9811689","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.
