摘要：
A data processing system has a dynamic type memory, a static type memory for storing data periodically read out, a central processing unit for transferring data to and from the two memories, an address generating circuit for periodically applying an address to the static type memory to read out the contents thereof, and an address selecting unit for exclusively selecting an address from the central processing unit or an address from the address generating circuit. In the system, the two memories are connected to the address selecting unit in order that the address selected by the address selecting means is supplied common to both the memories.
