MEMORY MANAGEMENT METHOD, MEMORY MANAGEMENT PROGRAM, AND INFORMATION PROCESSING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a memory management method that suppresses the occurrence of a bit error in a computer system that uses a nonvolatile memory as a main storage.SOLUTION: A virtual address is converted into a physical address and writing to a nonvolatile memory is performed. A memory management method includes the steps of: detecting a first page that is a page for which the number of times of writing exceeds an upper limit and a second page for which the number of times of writing does not exceed the upper limit, on the basis of the number of times of writing for each page in the nonvolatile memory; and changing a physical address of the first page into a physical address of the second page, for data indicating correspondence between the virtual address and physical address.SELECTED DRAWING: Figure 7
