Abstract: A method and an apparatus for pushing memory data from a memory to a push destination storage used to store data prefetched by a central processing unit (CPU) in a computing system are disclosed. In the method, a memory controller of the computing system periodically generates a push command according to a push period. Then the memory controller acquires a push parameter of to-be-pushed data according to the push command and sends at least one memory access request to memory according to the push parameter, where the at least one memory access request is used to request the to-be-pushed data from the memory. After receiving the to-be-pushed data that is sent according to the at least one memory access request by the memory, the memory controller buffers the to-be-pushed data and pushes the to-be-pushed data from the data buffer to the push destination storage.
