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.

Abstract: A memory refresh method is applied to a computer system including a processor, a memory controller, and a dynamic random access memory (DRAM). The memory controller receives a first plurality of access requests from the processor. The memory controller refreshes a first rank in a plurality of ranks at shortened interval set to T/N when a quantity of target ranks to be accessed by the first plurality of access requests is less than a first threshold and a proportion of read requests in the first plurality of access requests or a proportion of write requests in the first plurality of access requests is greater than a second threshold. T is a standard average refresh interval, and N is greater than 1. The memory refresh technology provided in this application can improve performance of the computer system in a memory refresh process.
