Abstract: A data processing system may include: a memory system including an error history region, the memory system suitable for storing in the error history region, error history data related to an internal error, and a host suitable for obtaining the error history data from the memory system by providing the memory system with an error history read command, performing failure analysis of the memory system on the basis of the obtained error history data, and controlling the memory system to clear at least a portion of the error history region by providing the memory system with an error history clear command, wherein the error history region is a memory region that is not able to be accessed with a logical address used by the host.

Abstract: According to an embodiment of the present technology, a storage device may include a memory device including a secure storage area for storing therein data to be accessed according to authentication; an access mode memory configured to store therein information of device access mode regarding an operation mode for the secure storage area; and a memory controller configured to receive a command regarding the secure storage area from an external host and process the command according to whether information of host access mode included in the command matches the information of the device access mode.

Abstract: A memory controller to control a memory device including a secure storage area may include a host interface configured to receive a command from a host, the command including information for authentication requesting access to the secure storage area; a processor configured to generate a device authentication code based on the information for the authentication; and a memory interface configured to access the secure storage area under control of the processor, and the processor may perform at least a portion of an operation of the device authentication code while the host interface or the memory interface receives data, following the command.
