Current is shunted from the first node, thereby lowering the second voltage to a third voltage. An isolation circuit block is then activated to couple the third voltage to a common node of the programmable anti-fuse block, the common node being coupled to a plurality of anti-fuses, each anti-fuse having a programmed state. A read signal is generated that causes a voltage potential representative of the programmed state of each anti-fuse to be latched into a corresponding latch element."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for reading a programmable anti-fuse element in a high-voltage integrated circuit","description":"In a method for reading a programmable anti-fuse block of a high-voltage integrated circuit a first voltage is applied to a first pin of the HVIC, the first voltage being lowered to a second voltage a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8487646","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.
