A storage means control apparatus of this invention includes a first processing unit for performing write processing in a first storage unit, a second processing unit for performing write processing in a second storage unit, a tag data control unit for managing tag data representing storage areas where the first processing unit has performed write processing in the first storage unit (101), another tag data control unit for managing another tag data representing storage areas where the second processing unit has performed write processing in the second storage unit, a priority data control unit for managing priority data representing a priority of each of the first and second processing units in units of storage areas of the second storage unit, a prevention data control unit for managing prevention data for preventing write processing in each storage area of the second storage unit using the priority data and the tag data, and a processing data updating unit for writing the data written in the first storage unit (101) in the second storage unit on the basis of the prevention data. With this arrangement, when each write control unit in a plurality of processing units performs write processing in the storage unit of the self processing unit, matching of stored contents among the units can be ensured.
