The controller manages a plurality of namespaces for storing a plurality of kinds of data having different update frequencies. The controller encodes write data by using first coding for reducing wear of a memory cell to generate first encoded data, and generates second encoded data to be written to the nonvolatile memory by adding an error correction code to the first encoded data. The controller changes the ratio between the first encoded data and the error correction code based on the namespace to which the write data is to be written."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Memory system and method of controlling nonvolatile memory","description":"According to one embodiment, a memory system includes a nonvolatile memory and a controller.
