    Abstract: A memory controller operating method includes executing a read operation directed to read data including a correctable data unit and an uncorrectable data unit, the uncorrectable data unit containing data that is uncorrectable using a normal error correction operation. The method further including; performing the normal error correction operation on the correctable data unit to generate partial read data, communicating dummy data instead of the uncorrectable data unit along with the partial read data from the memory controller to a host, and performing an enhanced error correction operation on the uncorrectable data unit while at least in part the dummy data and partial data are being communicated from the memory controller to the host.

    Abstract: A storage device that includes a nonvolatile memory device is described. The storage device includes areas and a controller. The controller receives a write command and data from an external host device. The controller then preferentially writes the data in an area associated with a turbo write based on a turbo write policy, or in an area not associated with a turbo write based on a normal write policy. The controller also receives a move command from the external host device and moves data stored in the area to a different area based on the move command.

    Abstract: A method of operating a storage device includes receiving, at the storage device, a meta information transfer command based on a data read request. The meta information transfer command is received from a host device. The method further includes receiving, at the storage device, a data read command corresponding to the data read request and the meta information transfer command. The data read command is received from the host device. The method further includes receiving, at the storage device, a plurality of meta data corresponding to the data read request and the meta information transfer command. The plurality of meta data is received from the host device. The method further includes performing a data read operation, at the storage device, based on the data read command and the plurality of meta data.

    Abstract: A memory system includes a host device including a host controller, and a memory device including a device controller and a non-volatile storage including a purge region and a memory region. The device controller communicates purge information associated with the purge region and including size information of the purge region. The host controller communicates a request for generating a first partition for a first logical unit in the memory region, and communicates a request for generating a second partition for a second logical unit in the purge region in response to the size information of the purge region.

    Abstract: A method of operating a storage device includes receiving, at the storage device, a meta information transfer command based on a data read request. The meta information transfer command is received from a host device. The method further includes receiving, at the storage device, a data read command corresponding to the data read request and the meta information transfer command. The data read command is received from the host device. The method further includes receiving, at the storage device, a plurality of meta data corresponding to the data read request and the meta information transfer command. The plurality of meta data is received from the host device. The method further includes performing a data read operation, at the storage device, based on the data read command and the plurality of meta data.
