MEMORY MANAGEMENT METHOD, MEMORY MANAGEMENT DEVICE AND MEMORY MANAGEMENT CIRCUIT

摘要

A memory controller (10) has a DIMM address conversion table in which physical addresses for a hypervisor (3) to uniquely identify storage areas that a memory (4) has, and memory addresses for a memory controller (10) to uniquely identify the storage areas are associated and stored. The memory controller (10) extracts, from the DIMM address conversion table (11), a physical address indicating the storage area of a DIMM in which an error is detected. Further, the memory controller (10) acquires, from the hypervisor (3), a physical address indicating a storage area in which information to be deleted by the occurrence of the error is stored, and extracts, from the DIMM address conversion table (11), the memory address associated with the acquired physical address. The memory controller (10) then moves the information stored in the storage area indicated by the extracted physical address to the storage area indicated by the extracted memory address.
