Upon receiving a data write command from the host device for writing data to the logical address stored in the logical defective cluster table, the control unit disables the reflection of writing of data for the logical address to the physical block."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Nonvolatile memory controller with logical defective cluster table","description":"A controller includes a control unit for controlling writing and/or reading of data to and from physical block based on a logical address from a host device, a logical defective cluster table for stor","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8484409","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.
