In some aspects, different doping is used in the MLC blocks than the SLC blocks. In some aspects, different isolation is used in the MLC blocks than the SLC blocks. Techniques are disclosed that apply different read parameters depending on how many times a block has been programmed/erased. Therefore, blocks that have been cycled many times are read using different parameters than blocks that have been cycled fewer times."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fabricating and operating a memory array having a multi-level cell region and a single-level cell region","description":"Techniques are disclosed herein for applying different process steps to single-level cell (SLC) blocks in a memory array than to multi-level cell (MLC) blocks such that the SLC blocks will have high e","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8503244","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.
