If an error is not detected for more than a predetermined period of time after the error patrol is started, the error patrol is stopped.Furthermore, if a single error is not detected for more than a predetermined period of time after the error patrol is stopped, the shortening of the refresh cycle is cancelled and returned to the original cycle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Memory device and refresh adjusting method","description":"When a single error of data is detected by an ECC circuit, a cycle adjusting unit provided on a memory board shortens a refresh cycle T1 of a refresh request generating unit to T2 and causes a patrol ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8539310","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.
