Abstract
A memory system is provided. The memory system includes a controller configured to refresh a memory array at a first temperature before a first refresh time that is acquired from a lookup table and corresponds to a time period for stored data in the memory array being lost at the first temperature. After the controller acquires a second refresh time from the lookup table, the controller resets a refresh time period to refresh the memory array before the second refresh time. The second refresh time corresponds to a time period for stored data in the memory array being lost at a second temperature different from the first temperature. The refresh time period corresponds to a time period after refreshing the memory array.
