An object-oriented system which deals with data and procedure integrally includes a memory having a real memory space which contains a set of object management information, a set of page management information, a fixed page region and an unfixed page region, a memory management section for managing these parts, a swap file for saving pages, and a method execution section which executes the procedure of an object. When loading the object into the real memory space, address-unfixed pages in the unfixed page region are allotted to the object and address-fixed pages in the fixed page region are allotted to the object at the time of execution. Consequently, the object can be accessed directly based on the physical address. The garbage collection and page swapping processes are implemented only for address-unfixed pages, and the overhead of object access operation can be reduced.
