An information processing apparatus includes a free page storage unit and a page allocating unit. The free page storage unit divides a memory region in a memory into pages of a plurality of different page sizes and manages the divided pages, and stores management information about an initialization state corresponding to an unused memory region in the memory. The page allocating unit selects a free page of a page size according to a requested region size or a requested page size from the free page storage unit when an allocation of the unused memory region is requested, and performs an initializing process on a memory region on which the initializing process has not been performed in a memory region corresponding to the free page using management information about the selected free page.
