Abstract: A scale-out device to control a group of non-volatile memory devices from among a plurality of non-volatile memory devices at a data storage device, includes a buffer and a scale-out controller. The buffer is configured to store address mapping information for the group of non-volatile memory devices, the group of non-volatile memory devices being a portion of the plurality of non-volatile memory devices at the data storage device. The scale-out controller is configured to control operation of only the group of non-volatile memory devices according to the address mapping information stored at the buffer.

Abstract: The data storage device includes scale-out storage devices and a controller configured to assign commands to the scale-out storage devices and re-assign the commands assigned to the scale-out storage devices based on state information output from a first scale-out storage device among the scale-out storage devices. Each of the scale-out storage devices includes a volatile memory device, a non-volatile memory device, and a scale-out controller configured to control the volatile memory device and the non-volatile memory device.

Abstract: A data storage device and a data processing system having the same are disclosed. The data storage device includes a nonvolatile memory and a controller, coupled to the nonvolatile memory, configured to receive first and second commands generated by a host and control an operation of the nonvolatile memory in response to the first command. The controller includes a core configured to receive and process the first command, a trace circuit corresponding to the core and configured to generate and output first data, based on pieces of information generated while the core processes the first command, and a trace controller configured to control output of the first data and second data differing from the first data, based on a result of performing at least one authentication control operation corresponding to the second command.

Abstract: A data storage device is provided. The data storage device includes a storage medium configured to store data blocks included in a stripe set, and a controller connected to the storage medium and configured to, decode a first data block disposed in a column among the data blocks, during a read operation of the first data block, and read first group data blocks disposed in the column among the data blocks, based on a read failure of the first data block.
