Abstract: A storage system shares a system memory of a host. An operation method of the storage system may include receiving a command including information about a shared memory from the host, receiving a stream command having no timeout from the host, and transmitting a first packet associated with the stream command to the host in response to the received stream command. The first packet includes information for accessing the shared memory.

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 storage device including a nonvolatile memory device is described. The storage device includes a controller that receives a write command and data from an external host device. The controller preferentially writes the data in an area based on a normal write policy when the data is associated with a normal write, and in an area based on a turbo write policy when the data is associated with a turbo write. The controller may also receive a read command, to read data from an area based on the read command, and output the data to the external host device. The controller may also move the data in response to move information of the read command when the read command is received together with move information.

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.
