摘要：
The present invention has been developed to carry out the dual-writing of data in cache memories at a higher speed through a single address designation for the improvement of processing performance. In the present invention, a host interface module produces addressing information for designating two written-in destinations, and a bridge module produces two transferred-to addresses and written-in addresses of the cache memories on the basis of the addressing information so that data to be written is transferred to two management modules corresponding to the two transferred-to addresses to be written at the written-in addresses of the cache memories of the management modules.
