The normal erase operation is performed to set a threshold voltage of a memory cell to an erase state which is lower than a first erase verification level. The quick erase operation is performed to set a threshold voltage of a memory cell to a pseudo erase state which is lower than a second erase verification level. The second erase verification level is higher than the first erase verification level."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Nonvolatle memory device and memory system having the same, and related memory management, erase and programming methods","description":"An erase method of a nonvolatile memory device includes setting an erase mode, and performing one of a normal erase operation and a quick erase operation according to the set erase mode.
