Abstract: A memory swapping method and apparatus are provided. The method includes: selecting n to-be-swapped-out pages; compressing the n to-be-swapped-out pages into n compressed blocks, and buffering the n compressed blocks in a compressed data buffer area; organizing at least one of the n compressed blocks into m to-be-written units; and writing the m to-be-written units into a swap area of a non-volatile storage device in a maximum of m batches, where at least one of the m to-be-written units is stored in a segment of continuous space in the swap area. The method reduces a quantity of write times during memory swapping, thereby prolonging a service life of the non-volatile storage device.
