The invention discloses a page hot degree based heterogeneous memory management method. The page hot degree based heterogeneous memory management method is characterized by including the steps of (1), as for memory pages of a heterogeneous memory, collecting total accessed read-write data, partial accessed read-write data and recent accessed read-write data in the memory pages, and storing the read-write data in a multi-level queue to form a page access record queue; (2), determining page hot degree values and hot degree values according to the partial read-write data and the recent read-write data, and sequentially reserving N pages with page hot degree values, exceeding a preset hot degree threshold value, as hot pages and N pages with page cold degree values, exceeding a preset cold degree threshold value, as cold pages; (3), selecting one optional cold page to be combined with each hot page, estimating energy-saving values, sequencing the energy-saving values in a descending sequence, selecting the cold and hot pages to be matched, and migrating the pages according to match results so as to reduce energy consumption. By the aid of the page hot degree based heterogeneous memory management method, high performance of a dynamic random access memory can be used fully, and overall performance of a heterogeneous memory system can be improved.
