A portion near the center of the set of n-type doped regions OD serves as a source/drain region shared by two gates, whereas portions near both ends thereof serve as source/drain regions for respective gates. Each of the source/drain regions is connected to a storage electrode SN of a memory cell capacitor via a storage contact CA or is connected to a sub bit line or a main bit line via a sub-bit-line contact CH and/or a via of a metal interconnection. A pattern formed of four memory cell gates TG and four bit-line connecting gates SW is repeated."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor storage device","description":"In a semiconductor storage device, either two memory cell gates TG or a memory cell gate TG and a bit-line connecting gate SW are formed in every set of n-type doped regions OD at the intersections wi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8488358","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.
