Abstract
A memory system includes a memory device, a controller and a timer circuit. The controller is configured to refresh the memory device according to a first refresh time. The timer circuit is configured to count a first refresh time period. When a first operation temperature of the memory device changes to a second operation temperature, the controller is further configured to acquire a second refresh time, for refreshing the memory device, corresponding to the second operation temperature, and configured to refresh the memory device according to the second refresh time, and the controller is further configured to reset the timer circuit to count a second refresh time period different from the first refresh time period after the controller acquires the second refresh time.
