A memory channel failure is located and corrected, or alternatively up to c chip failures are corrected and up to d chip failures are detected in the presence of up to u chips that are marked as suspect. A first stage of decoding is performed that results in recovering an estimate of correctable errors affecting the data or in declaring an uncorrectable error state. When an uncorrectable error state is declared, a second stage of decoding is performed to attempt to correct u erasures and a channel error in M iterations where the channel location is changed in each iteration. A correctable error is declared in response to exactly one of the M iterations being successful."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Correcting memory device and memory channel failures in the presence of known memory device failures","description":"Correcting memory device (chip) and memory channel failures in the presence of known memory device failures.
