摘要

Further optimization of region collection efficiency is realized by GC processing that divides and manages the memory region. To this end, the computer is a computer having an arithmetic device and a memory, comprising: a storage unit for storing reference source information of data stored in a plurality of storage areas allocated to the memory for each of the storage areas; And a control unit which determines that the updated reference source information is a storage area different from the reference source information recorded in the storage unit as a releasing target area.
