Abstract: A storage device includes: a non-volatile memory device; and a storage controller for receiving a first Protocol Information unit (PIU) including a first merge message from an external device, and performing, based on the first PIU, at least one of a sense operation of reading first data stored in a memory block of the non-volatile memory device and a select operation of storing, in the memory block, second data received from the external device. The first PIU includes a basic header segment commonly included in PIUs transmitted/received between the external device and the storage controller, and a first Extra Header Segment (EHS) including the first merge message.

Abstract: A storage device includes a nonvolatile memory device including a replay protected memory block; and a memory controller for, as a submission command requesting access to the replay protected memory block is received from an external host including a host memory having a plurality of Physical Region Pages (PRPs), acquiring a host replay protected memory block data frame stored in one of the plurality of PRPs included in the external host and accessing the replay protected memory block. The submission command may include information on a position at which the memory controller is to store a response to the submission command among the plurality of PRPs.

Abstract: A memory controller includes: a host interface configured to receive, from a host, a diagnostic command for requesting performance of a self-test operation; and a processor configured to perform the self-test operation on a memory device, and generate a response corresponding to the diagnostic command, wherein the host interface is configured to transmit, to the host, the response including: a basic header segment commonly included in protocol information units transmitted/received between the memory controller and the host; and an extra header segment including result information indicating a result of the self-test operation.

Abstract: Provided herein may be an electronic device and a method of operating the same. The electronic device may include a memory device, and a controller configured to receive an inbound protocol information unit (PIU) from an external device and control the memory device based on the inbound PIU, wherein the inbound PIU includes a basic header segment including information about an extra header segment (EHS) length, and an extra header segment defined by the EHS length, and wherein the controller is configured to generate an error message depending on whether the PIU includes an error related to the extra header segment.
