During a first period after the first and second memory cells are simultaneously accessed, the control circuit controls the first switch to conduction state so that the first sense amplifier amplifies the first signal and controls the second switch to non conduction state. During a second period after sensing of the first sense amplifier finishes, the control circuit controls the second switch to conduction state so that the second sense amplifier amplifies the second signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device and control method thereof","description":"A semiconductor device has a hierarchical bit line structure and comprises first and second local bit lines transmitting first and second signals of first and second memory cells corresponding to a se","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8520449","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.
