According to the present invention, where current data to be written to a nonvolatile memory corresponds to an address cache hit is determined. If the current data to be written corresponds to an address cache hit, the current data are written to a designated location in the nonvolatile memory different from a destined location in the nonvolatile memory. If the current data to be written corresponds to an address cache miss, the current data are written to the destined location in the nonvolatile memory. In another embodiment, the wear leveling control technique also includes address rotation process to achieve long-term wear leveling as well."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method of wear leveling for storage class memory using address cache","description":"A method and apparatus of wear leveling control for storage class memory are disclosed.
