The control circuit allows an operation to be performed on the targeted first memory block in accordance with the command signal when the targeted first memory block is not indicated as being defective, and blocks the operation to be performed on the targeted first memory block when the targeted first memory block is indicated as being defective."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Memory system that handles access to bad blocks","description":"A memory system includes a plurality of pins for connection to the outside of the memory system, one of the pins being configured to receive a command signal, a memory cell array including a plurality","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9728275","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.
