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.
Claims20
A storage device, comprising:
- a memory device configured to include a replay protected memory block (RPMB) requiring authenticated access;
- and
- a memory controller configured to receive a first data packet for the RPMB and data corresponding to the first data packet from outside, to perform authentication operation based on the first data packet, to generate a second data packet including information indicating that a response type of the second data packet is a write response and to provide a second data packet to the outside.
A method of operating a storage device including a memory device including a replay protected memory block (RPMB) requiring authenticated access and a memory controller controlling the memory device, the method comprising:
- receiving a first data packet for the RPMB from outside, wherein the first data packet includes a first authentication code and information regarding a request type indicating the request type of the first data packet is a write request;
- receiving data for storing in the RPMB from the outside, after the receiving the first data packet;
- and
- transmitting a second data packet, which includes information regarding a response type indicating the response type of the second data packet is a write response.
A host device in communication with a storage device including a replay protected memory block (RPMB), the host device comprising:
- an application processor configured to output a first data packet for a replay protected memory block (RPMB) requiring authenticated access and data corresponding to first data packet and to receive a second data packet from the storage device;
- and
- a memory module configured to temporarily store the data to be store in the RPMB,
- wherein the first data packet includes a first authentication code and information regarding a request type indicating the request type of the first data packet is a write request, and
- wherein the second data packet includes information regarding a response type indicating the response type of the second data packet is a write response.
