Loss balancing method based on storage type memory

The invention relates to a storage class memory (SCM) wear leveling method, which comprises the following steps of: distinguishing the data type of data according to the wear force of the data, distinguishing the unit type of a storage unit according to the wear degree of the storage unit, and adjusting the storage position of the data according to the data type of the data and the unit type of the storage unit. The loss balancing method provided by the invention is suitable for the storage device of the storage type memory, the service life of the storage device can be greatly prolonged, and a solid foundation is laid for large-scale commercial application of a storage system based on the storage type memory. 本发明涉及一种存储类内存(Storage Class Memory，SCM)的损耗均衡方法，包括根据数据的损耗力区分数据的数据类型，根据存储单元的损耗度区分存储单元的单元类型，并通过数据的数据类型与存储单元的单元类型调整数据的存储位置。本发明提供的损耗均衡方法适用于存储类内存的存储设备，能极大提高存储设备的寿命，为基于存储类内存的存储系统大规模商业化应用奠定了坚实基础。
