A memory page management method is provided. The method includes receiving a state-change notification corresponding to a state-change page, and grouping the state-change page from a list to which the state-change page belongs into a keep list or an adaptive LRU list of an adaptive adjusting list according to the state-change notification; receiving an access command from a CPU to perform an access operation to target page data corresponding to a target page; determining that a cache hit state is a hit state or a miss state according to a target NVM page address corresponding to the target page, and grouping the target page into the adaptive LRU list according to the cache hit state; and searching the adaptive page list according to the target NVM page address to obtain a target DRAM page address to complete the access command corresponding to the target page data.

Memory controller and memory page management method

The present disclosure provides a memory system, a method of operating memory, and a non-transitory computer readable storage medium. The memory system includes a memory chip and a controller. The controller is coupled with the memory chip, which the controller is configured to: receive a first data corresponding to a first version from a file system in order to store the first data corresponding to the first version in a first page of the flash memory chip; and program the first data corresponding to a second version in the first page in response to the first data of the second version, which the second version is newer than the first version.
