The plurality of structures of the semiconductor chip includes a set of common structures which is the same for all of the semiconductor chips of the set, and a set of non-common structures, wherein the non-common structures of the semiconductor chip of the subset is different from a non-common circuit of the semiconductor chips in every other subset. At least a first portion of the non-common structures and a first portion of the common structures form a first non-common circuit, wherein the first non-common circuit of the semiconductor chips of each subset is different from a non-common circuit of the semiconductor chips in every other subset. At least a second portion of the non-common structures is adapted to store or generate a first predetermined value which uniquely identifies the first non-common circuit, wherein the first predetermined value is readable from outside the semiconductor chip by automated reading means."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secure chips with serial numbers","description":"An electronic device comprising a semiconductor chip which comprises a plurality of structures formed in the semiconductor chip, wherein the semiconductor chip is a member of a set of semiconductor ch","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10522472","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.
