In a first period, each sense amplifier amplifies a signal of one of adjacent global bit lines, and in a second period, each sense amplifier amplifies a signal of the other thereof. Accordingly, coupling between the global bit lines can be suppressed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device having hierarchical bit line structure","description":"A semiconductor device of the invention comprise a memory cell array configured with hierarchical local bit lines and global bit lines, in which there are provide local bit lines, global bit lines, sw","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8472272","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.
