METHOD FOR MIGRATING MEMORY DATA, COMPUTER AND DEVICE

摘要

A method for migrating memory data, a computer and a device are provided by embodiments of present invention, used for migrating the memory data in the computer. The operation system of the computer can suspend the current executed task after obtaining a first trigger instruction in order to execute the migration of the memory data, determine a source memory card whose memory data is to be migrated, determine a backup memory card for the source memory card, indicate a memory controller of the source memory card to migrate the memory data in order to make the memory controller of the source memory card read the memory data of the source memory card on the basis of the indication of the operation system, and write the read memory data of the source memory card into the backup memory card in order to migrate the memory data of the source memory card in the case that the computer is power on, thereby realizing online maintenance of a faulty memory card and solving the problem in the prior art that replacement or maintenance of the faulty memory card can be performed only when the whole computer is power down.
