ABSTRACT:
A memory management apparatus suitable for reducing amount of memory usage and simplifying programs is provided. When an area allocation request has been inputted, an unused area having a size that is determined by area size information included in the area allocation request is searched for as a candidate area on the basis of a memory management table400. And overlap flag corresponding to an adjoining area that is contiguous with the candidate area in its lower address orientation is read from the memory management table400, and, based on the overlap flag, it is determined whether or not the adjoining area is an area that allows overlapped allocation. If it is determined the area is an area allowing overlapped allocation, a used area that overlaps with the adjoining area is allocated.
