The virtual memory managing system of the present invention includes a virtual memory managing unit that manages a virtual memory system by combining swap-out in page units and swap-out in task units. The virtual memory managing unit includes: a memory area reserving unit that creates and manages swap management tables corresponding to a memory area reserve requests from tasks and reserves memory areas for the memory area reserve requests; a swap-out control unit that, when swap-out becomes necessary, determines whether swap-out should be carried out in page units or batch swap-out should be carried out in task units, and based on this determination, controls swap-out and sets information in the swap management tables; and a swap-out object limiting means that, when batch swap-out is to be carried out in task units, carries out a limited swap-out based on the swap management tables.
