In the code matrix, a bitwise XOR of any two codes in the first portion of the code matrix or any two codes in the second portion of the code matrix results in a code that is either not in the code matrix or is in the other portion of the code matrix. Thus, a miscorrected double bit error in one portion causes a bit to be toggled in the other portion instead of creating a triple bit error."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Memory device on-die error checking and correcting code","description":"In a system where a memory device performs on-die ECC, the ECC operates on N-bit data words as two (N/2)-bit segments, with a code matrix having a corresponding N codes that can be operated on as a fi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9817714","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.
