The present invention discloses an NAND flash memory-oriented page replacement method, belonging to the field of data storage. According to the method, a cold clean page linked list and another hybrid page linked list respectively manage cold clean pages and other cache pages, and a reserved ghost page linked list records metadata information of recent obsolete cache pages; before page visit processing, initialization is performed first, if the page is hit in another hybrid page linked list or the cold clean page linked list, the page is marked a hot page and is moved to a recently visited terminal of another hybrid page linked list; if the page is hit in the ghost page linked list, record of the page in the ghost page linked list is deleted, a new cache page is allocated to the page and is marked a hot page, and the page is moved to the recently visited terminal of another hybrid page linked list; and finally, if it is determined that the page is read or write request, the data is read or written in the cache page and is returned. Through adoption of the method, flash memory write operation is reduced, and a higher cache hit ratio is maintained as far as possible.
