The method includes applying a first default read voltage included in default read voltages to word lines coupled to the first memory cells, and measuring a first ratio of first on-cells, each of which has a threshold voltage smaller than or equal to the first default read voltage, among the first memory cells, and modifying the first default read voltage based on the first ratio and a first reference value corresponding to the first default read voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of determining default read voltage of non-volatile memory device and method of reading data of non-volatile memory device","description":"A method of determining a default read voltage of a non-volatile memory device which includes a plurality of first memory cells, each of which stores a plurality of data bits as one of a plurality of ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9666292","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.
