The method includes selecting a memory block to be erased using a power supply voltage; unselecting a remaining memory block, other than the selected memory block, using a negative voltage; setting a bias condition to reduce leakage currents of the unselected memory block; and performing an erase operation on the selected memory block."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Nonvolatile memory device and method of erasing nonvolatile memory device","description":"A method is provided for erasing a nonvolatile memory device, including multiple memory blocks formed in a direction perpendicular to a substrate, each memory block having multiple strings connected t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9659662","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.
