PROBLEM TO BE SOLVED: To solve the problem that an initialization process of page contents is certainly performed when allocating a page of a memory managed in page units and it causes large overhead thereby occupying the whole system. SOLUTION: About the page allocated for executing a program, when acquiring the page initialized in time of a start first after the start, the initialization process of the page is not performed. About the page allocated when executing the program again, when the same page as before is allocated to the same program, the initialization process of the page is not performed. When safety of the page allocated to the program is low and only when reliability of the program allocated with the page is low, the initialization process of the page is performed. By these means, a total amount of the initialization process of the page is reduced. COPYRIGHT: (C)2006,JPO&NCIPI
