The device further includes a plurality of interconnects disposed on the substrate in the sense amplifiers, extending in a first direction parallel to the surface of the substrate, being adjacent to one another in a second direction perpendicular to the first direction, and arranged in the same interconnect layer. At least one of the second device regions includes first and second stripe portions extending in the first direction, being adjacent in the second direction, and having stripe shapes, and a connecting portion disposed to connect the first stripe portion and the second stripe portion. The device further includes a source contact disposed on the connecting portion, and electrically connected to one of the interconnects."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Nonvolatile semiconductor memory device","description":"In one embodiment, a nonvolatile semiconductor memory device includes a substrate provided with a memory cell part and sense amplifiers on a surface of the substrate, first isolation regions and first","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8514602","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.
