Abstract: A memory allocation method and apparatus is disclosed. The method includes: obtaining unoccupied mirrored memory in an initial mirrored memory, where the initial mirrored memory is indicated by a mirrored memory address range that is provided by an BIOS of a computer system to the an OS of the computer system during initialization of the OS; performing detection on data requiring memory allocation; and when detecting that the data is data to be stored in mirrored memory, allocating, from the unoccupied mirrored memory, the mirrored memory to the data to be stored in the mirrored memory. The memory allocation method can accurately find the mirrored memory, and allocating the mirrored memory to the data that needs to be stored in the mirrored memory. Therefore, this method ensures usage efficiency of the limited mirrored memory.
