Claim 10:
11. A method for operating a memory controller for controlling a memory device in response to a read request from a host, the method comprising:
receiving map data including a plurality of mapping entries read from the memory device;
transferring the plurality of mapping entries to both a buffer memory and a map data controller included in the memory controller;
concurrently with transferring the plurality of mapping entries to the buffer memory, detecting, by the map data controller, a mapping entry of a requested logical block address corresponding to the read request among the plurality of mapping entries; and
outputting, by the map data controller, an interrupt signal representing that the mapping entry of the requested logical block address has been detected in response to detection of the mapping entry of the requested logical block address.
