Abstract: A page swap method, a storage system, and an electronic device as applied to the field of memory management technologies are provided. The method includes determining, from a least recently used LRU linked list, a to-be-swapped-out first swap-out page of a memory device, determining a second swap-out page from the LRU linked list based on the first swap-out page, and when the first swap-out page is swapped out of the memory device, swapping out the first swap-out page and the second swap-out page to a swap device.

Abstract: This application provides a memory management method and a terminal device. According to the method, a frequently accessed memory page and a rarely accessed memory page that are required for starting and using an application may be determined by using a memory page on which a page exception occurs in a target running application. A terminal retains, in a memory, the memory page that is required for starting and using the application, to resolve a problem that freezing occurs when an application that runs in a background is started again, and improve keepalive performance of the application. The terminal migrates the rarely accessed memory page to a swap partition of a storage, to save memory resources.
