Abstract
A memory allocation method and a device, where the method is applied to a computer system including a processor and a memory, and comprises, after receiving a memory access request carrying a to-be-accessed virtual address and determining that no memory page has been allocated to the virtual address, the processor selecting a target rank group from at least two rank groups of the memory based on access traffic of the rank groups. The processor selects, from idle memory pages, a to-be-allocated memory page for the virtual address, where information about a first preset location in a physical address of the to-be-allocated memory page is the same as first portions of address information in addresses of ranks in the target rank group.
