Abstract
PURPOSE:To normally access a main storage device without changing the interface of the main storage device, by merging and storing read data and write data in response to a write request when a cache cannot be used. CONSTITUTION:A cache memory device 1 of the swap system is provided with a buffer 24 where store data from the request source and read data from a main storage device (MMU) 4 are merged and held. Thus, the MMU 4 is normally accessed without changing the interface to the MMU 4, namely, with the interface only for block read and block store even if all of a data array (DA) 22 of the cache memory device 1 cannot be used.
