MEMORY MANAGEMENT METHOD

摘要

A method for managing main memory including DRAM and NVRAM in a computer depending on the operation state of the computer is provided. The method includes: (a) upon start of the computer, loading a program and the like into the DRAM, and loading predetermined read-only data and the like into the NVRAM; (b) in a state transition from a normal operation to a suspend state, moving data in the DRAM to the NVRAM; (c) in a state transition from the suspend state to the normal operation, reading data from the NVRAM for program execution; (d) in the case where a data write to the NVRAM occurs, stopping the data write, and moving data in a data area of the NVRAM subjected to the data write, to the DRAM; and (e) performing the data write to the DRAM to which the data has been moved.

1. A method for managing main memory comprising DRAM and NVRAM in a computer depending on a transition of an operation state of the computer, the method comprising:
upon start of the computer, loading at least one of a first program and a first data into the DRAM, and loading at least one of a second program and a second data into the NVRAM; in a state transition from a normal operation of the computer to a suspend state of the computer, moving the first data in the DRAM to the NVRAM on a page basis; in a state transition from the suspend state of the computer to the normal operation of the computer, reading the first data from the NVRAM on a page basis for program execution by the computer; in the case where a first data write to the NVRAM on a page basis occurs while reading the first data from the NVRAM on a page basis, stopping the first data write, and moving the first data in a data area of the NVRAM subjected to the first data write, to the DRAM on a page basis; and performing the first data write on a page basis to the DRAM to which the first data has been moved.
