Abstract
A controller may include a first map buffer and a second map buffer suitable for storing map data and hit counts respectively corresponding to the map data, wherein each of the hit counts represents a number of accesses to data stored in a memory device by using a corresponding one among the map data, and wherein the controller swaps the map data and corresponding hit counts between the first and second map buffers such that the first map buffer stores relatively higher hit counts and corresponding map data than the second map buffer.
