Thus, in the memory unit, each of a voltage difference between the first deep well and the first well and a voltage difference between the second deep well and the second well is made smaller than a voltage difference (18 [V]), at which a tunneling effect occurs, and accordingly a junction voltage between the first deep well and the first well and a junction voltage between the second deep well and the second well are low."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Non-volatile semiconductor storage device","description":"In a memory unit, voltages required for operations of a capacity transistor in a first well and a writing transistor in a second well are separately applied to a first deep well and a second deep well","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9830989","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.
