  • Memory management method and computer using the method
    Patent number: 8589653
    Abstract: Memory management by garbage collection involves a memory area that is allocated in a computer. Data is created in the memory area in accordance with a program executed by a processor of the computer, and it is checked whether or not data necessary to execute the program exists in the memory area to be released, in response to an explicit instruction to release the memory area. As a result of the check, if data necessary to execute the program does not exist in the memory area, the memory area is released. As a result of the check, if data necessary to execute the program exists in the memory area, the data is moved to a memory area different from the memory area to be released.
