Abstract
A storage device includes a storage region in which first data is stored and that is accessed using a first virtual address, and a memory controller configured to control stored data stored in the storage region. The memory controller predicts second data to be accessed using a second virtual address based on the first virtual address, prefetches the second data into an external device, and modifies a physical address mapped to the second virtual address so that the prefetched second data is accessible by a host in communication with the storage device.
