PURPOSE:To use effectively a prescribed logical memory space whose size is limited, by dividing the logical memory space into a common memory area and a bank memory area, and storing a common module and an individual module of a program, and only a bank control module in the bank memory area and the common memory area, respectively. CONSTITUTION:When assigning a memory, a common module 4 is provided in a bank memory area 2. In such a memory array, when executing a program, a main routine in a bank '0' is started first, and thereafter, individual modules 5-(n) are executed successively through a bank control module 3. Also, a call of the common module from the individual module is also executed through the bank control module 3. In this way, by storing the common module 4 in the bank memory area 2, a common memory area 1 can be reduced, and the bank memory area 2 is extended and widened, therefore, the storable quantity of the individual modules 5-(n) increases, and the utilizing efficiency of the memory becomes large.
