Abstract
A memory manager secures memory areas according to requests from programs and sets ranks designated by the programs to the secured memory areas. The memory manager selects a memory area released on the basis of the rank of each memory area, from the secured memory areas, when an available capacity of a main storage device is insufficient. The memory manager releases the selected memory area and secures a new memory area. The present disclosure can be applied to an embedded apparatus.
