Abstract
Embodiments of the present specification provide a data migration method based on a heterogeneous memory, the heterogeneous memory comprising a high-speed memory and a low-speed memory. The method comprises: determining access frequency information of memory pages by monitoring a memory access operation for the heterogeneous memory; and migrating, under a first condition, cold data in the high-speed memory to the low-speed memory, the cold data being determined based on the access frequency information.
