Abstract: A memory management method and a device, where the method includes: receiving a memory access request, where the memory access request carries a virtual address; determining a page fault type of the virtual address if finding, in a translation lookaside buffer TLB and a memory, no page table entry corresponding to the virtual address; allocating a corresponding page to the virtual address if the page fault type of the virtual address is a blank-page-caused page fault, where the blank-page-caused page fault means that no corresponding page is allocated to the virtual address; and updating the page table entry corresponding to the virtual address to the memory and the TLB. The memory manager does not generate a page fault when a blank-page-caused page fault occurs, but allocates a corresponding page to the virtual address. Therefore, a quantity of occurrences of the page fault is reduced, thereby improving memory management efficiency.

Abstract: A method for accessing an extended memory, a device, and a system are disclosed. According to the method, after receiving a first memory access requests from a processor system in a computer, an extended memory controller sends a read request for obtaining to-be-accessed data to the extended memory and return, to the processor system, a first response message indicating the to-be-accessed data has not been obtained. The extended memory controller writes the to-be-accessed data into a data buffer after receiving the to-be-accessed data returned by the extended memory. After receiving, from the processor system, a second memory access request comprising a second access address, the extended memory controller returns, to the processor system, the to-be-accessed data in the data buffer in response to the second memory access request, wherein the second access address is different from the first access address and points to the physical address of the to-be-accessed data.
