CONSTITUTION:Own-site cache information such as D11'' and other-site cache information such as D21' and D22' are retained in internal memory cache areas, e.g., an area 6. Moreover, an external memory cache area such as an area 8 is provided, and at least other-site cache information D22', which has been ejected in the internal memory cache area 6, is retained as information D22''' therein. |
