The controller repeatedly performs an erase voltage application process for data stored in a target area in the memory. The controller performs an erase verification process for determining whether the erase is successful using erase verification voltage. The controller determines whether an erase time is longer than a first threshold value. The controller sets the target area to a use prohibition state when the erase time is longer than the first threshold value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Memory system controlling data erase for nonvolatile memory and control method for erasing data","description":"According to one embodiment, a memory system includes a memory and controller.
