Abstract: A storage controller includes a host interface configured to communicate with a host, a buffer memory configured to buffer data read from a non-volatile memory, a cache memory including a plurality of cache lines and configured to store the data in at least one of the plurality of cache lines, and a cache controller configured to manage a status bitmap. The status bitmap indicates priority information of the plurality of cache lines according to an operation corresponding to a request received from the host interface, and the cache controller is further configured to select a victim cache line, among the plurality of cache lines, to be replaced based on the status bitmap. In this case, the operation corresponding to the request corresponds to one of normal read, prefetch, read-after-read, and read-after-prefetch.
