In writing, a current corresponding to multilevel data is supplied to the transistor in the memory cell and stored as the gate-drain voltage of the transistor in the memory cell. In reading, a current is supplied to the transistor in the transistor with the stored gate-drain voltage, and the multilevel data is obtained from the voltage supplied to generate a current that is equal to the current."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor memory device","description":"To provide a memory cell for storing multilevel data that is less likely to be affected by variations in characteristics of transistors and that is capable of easily writing multilevel data in a short","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9679628","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.
