A method includes de-allocating a first region of a group of regions of the memory during a wear leveling process based on a determination that the first region is associated with a first tag of a set of tags. Each region of the group of regions is assigned to a tag of the set of tags based on a health metric associated with the region. The health metric is based on a bit error rate (BER), a program/erase cycle (PEC) count, a PEC condition metric, or a combination thereof. In response to selecting the first region, information is copied from the first region to a second region of the memory during the wear leveling process."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Tag-based wear leveling for a data storage device","description":"A data storage device includes a memory.
