PROBLEM TO BE SOLVED: To solve the problem that when the size of a page is switched in the virtual memory management function, there exists too enormous an overhead in connection with the size of a page switched by a page access information unit which manages the referential and update state in each page. SOLUTION: This invention relates to a multiprocessor system provided with information on the page access in which a main memory is managed on a page-unit basis and the update state in a page is indicated in each page, characterized in that where memory access is implemented in a state in which the size of a page in the main memory undergoes dynamic alterations under operation, information on the page access can be managed even in a state of mixed pages different in size in the main memory in view of the fact that a change is made from 1 to 1 into 1 to n so that the correspondence can be completed between the unit of a page managed in response to the size of a page altered and information on the page access.
