PROBLEM TO BE SOLVED: To rearrange the areas of user's virtual space by utilizing a virtual space management table and to effectively utilize the virtual space by using the same address as that obtained before rearrangement. SOLUTION: The dynamic virtual space address conversion system is provided with a 1st area securing means 21 for acquiring an unallocated virtual address from the virtual space management table 31, securing a memory area in the user's virtual space 32 and registering the virtual address in the table 31 as a real virtual address together with its area size. When the memory area can not be secured in the user's virtual space 32, an area rearrangement processing means 22 is allowed to execute the rearrangement processing of the space 32 and a 2nd area securing means 23 is allowed to secure the memory area again after the rearrangement processing and register the virtual address in the table 31.
