Abstract: A controller configures a map table including a map entry associating different address schemes with each other. The controller is configured, for performing map table configuration, to find a target map entry among previous map entries in the map table, merge the current map entry into the target map entry to generate a merged map entry when the target map entry is found, and store the merged map entry in the map table. The target map entry and a current map entry include at least some information which is overlapped.
