PROBLEM TO BE SOLVED: To solve the bottleneck of a memory access in a Montgomery arithmetic circuit while using a 2-ports or single-port general memory. SOLUTION: The circuit comprises two memories 7 and 8, and the variables necessary to be read from the memories of variables necessary for operation are recorded in different memories. In the same reading stage of pipeline processing, a variable is read from the memory 7 to a resister 5, and the other variable is read from the memory 8 to the other resister.
