Abstract: A memory system, comprises a nonvolatile memory comprising multiple memory cells, and a memory controller configured to control respective cell levels of the memory cells by assigning a logical address of each memory cell to one of multiple address groups according to a frequency with which the logical address has been accessed, determining a cell level for each address group, and controlling each memory cell to have the cell level of the address group to which its logical address is assigned.
