Abstract

PURPOSE:To improve the system efficiency at the time of copying with a simple constitution in a multiplexed storage system, by using a refresh cycle as the copying cycle at the time of copying. CONSTITUTION:When a main storage device 30a makes a copying request to another main storage device 30b, a memory controlling section 313a delivers a copying address of a copying address counter to a memory module 301a and the main device 30b in the first half of the refreshing cycle. In the device 30b, this address is held by an address register 305b. On the other hand, in the main device 30a data reading from the module 301a is performed and read data are held by a data register 303b of the main device 30b. During this period, a memory module 301b is refreshed in the device 30b. Subsequently, in the second half of the refreshing cycle, the module 301a is refreshed in the device 30a, and, in the device 30b, contents held by the registers 305b and 303b are given to the module 301b and writing is performed.
