Abstract
A processor generates stream information indicating a stream of access on the basis of the positional relationship on a storage device among a plurality of accessed first data blocks. The processor associates sequence information representing the positional relationship on the storage device with a plurality of second data blocks prefetched in a memory on the basis of the stream information. When a certain second data block is accessed, the processor searches for another second data block that is determined to be earlier in the order of access made by the stream than the certain second data block, on the basis of the sequence information. The processor removes the found second data block from the memory.
