A difference in voltage between the fourth target voltage and the third target voltage may be greater or less than a difference in voltage between the third target voltage and the second target voltage and/or a difference in voltage between the second target voltage and the first target voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data retention charge loss and read disturb compensation in solid-state data storage systems","description":"A data storage device includes a solid-state memory including memory cells and a controller configured to perform a first programming scheme that programs a first subset of the cells to a first voltag","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9620226","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.
