PROBLEM TO BE SOLVED: To provide a cache system capable of efficiently transferring data among a plurality of caches, when connecting the plurality of caches on a one-to-one basis to a plurality of processors. SOLUTION: The cache system has the plurality of processors 101-103; the plurality of caches 111-113 connected in a one-to-one manner plurality of processors; a controller 120, connected to the plurality of caches for controlling the data transfer between the plurality of caches; and an information memory for storing first information 121-123, showing the use oldness order of entries in own cache and the other caches for each processor.
