Abstract

An electronic device includes a memory controller selecting map data to be output to a host. The memory controller includes an address counter and a map data selector. The address counter counts a number of times a logical block address corresponding to a request is received based on the request received from the host and outputs an activation signal indicating that an index to which the logical block address belongs is an activation index when an activation count corresponding to the index is equal to or greater than a preset value, the activation count being generated based on a counting result. The map data selector selects map data to be output to the host based on the activation signal. The address counter decreases the activation count by a preset size when a size of the selected map data exceeds a storage capacity of the host allocated for storing map data.
