Abstract: Embodiments of the present invention provide a memory management method, a memory management apparatus and a NUMA system. The memory management method includes: determining, according to a memory demand information which includes memory demand information sent by a processor, whether a memory controller meeting the memory demand information exists in a local processing node which the processor; and if exists, determining, in the memory controller meeting the memory demand information, a memory management area meeting the memory demand information, and allocating the memory management area meeting the memory demand information to the processor. Therefore, the memory controller and the memory management area do not need to be determined in a processing node that does not meet the requirements, which can rapidly find a storing area meeting the requirements, and improve the memory allocation efficiency.
