Abstract
Provided herein may be a storage device and a method of operating the same. The method of operating a storage device including a replay protected memory block (RPMB) may include receiving a write request for the RPMB from an external host, selectively storing data in the RPMB based on an authentication operation, receiving a read request from the external host, and providing result data to the external host in response to the read request, wherein the read request includes a message indicating that a read command to be subsequently received from the external host is a command related to the result data.
