In this way, when there is a failure in the memory cell, it is possible to prevent the semiconductor device from passing the test as a result of the determination that the actual value is the same as the expected value in the test even if there is no potential difference in the bit line pair."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device","description":"A semiconductor device includes a word line coupled to a mask ROM memory cell, a bit line pair coupled to the memory cell, a differential sense amplifier for amplifying the potential difference of the","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9818490","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.
