ABSTRACT:
A computer system is provided, wherein a storage device having a flash memory as the main medium is given a cache memory with a high hit rate even in a small capacity and less access overheads, high-speed writing to the flash memory is attained, and the number of rewriting is reduced: wherein a processing device, a cache memory and a flash memory for data via the cache memory to be written in response to a request from the processing device are provided; and a line size of an entry to the cache memory is 1/N (note that N is 2 or larger integer) of an actual page size as a writing unit of the flash memory.
