The check operation includes comparing the first threshold voltage with a first lower-limit reference voltage level, and performing a program operation on the first select transistor when the first threshold voltage is lower than the first lower-limit reference voltage level. When the first threshold voltage is equal to or higher than the first lower-limit reference voltage level, the check operation on the first threshold voltage is ended."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Non-volatile memory devices and methods of operating the same","description":"A method of operating a non-volatile memory device includes selecting a first select transistor from among a plurality of select transistors included in a NAND string, and performing a check operation","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9747997","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.
