Abstract: Disclosed is a storage device. The storage device includes: a memory device; a buffer memory configured to store partial data among data stored in the memory device; and a memory controller configured to determine prefetch logical addresses expected to be received sequentially after sequential logical addresses are received from a host, to read prefetch data corresponding to the prefetch logical addresses from the memory device to store the prefetch data as a prefetch group of in the buffer memory, and to release the prefetch group from the buffer memory in response to a logical address discontinuous with the logical addresses being received from the host.
