When being data housing request, although the data is housed in the address which the pointer which points to the forefront of the empty territory shows when being data removal request, the data is removed from the data housing territory which the oldest index shows. In addition, when being condensing request, as the data after making the evacuation territory evacuate once, the data which is evacuated in the territory where it continues from the address which the pointer which points to the forefront of the empty territory shows is restored from the data housing territory, equal to size amount of the data housing territory which requires the pointer which points to the forefront of the empty territory for the restoration of the data advances. By the fact that it makes this way, during condensing processing, it is possible to house the data in the address which the pointer which points to the forefront of the empty territory shows.
