    Abstract: A storage device includes a first non-volatile memory comprising a plurality of first banks having a plurality of first addresses and a second non-volatile memory comprising a plurality of second banks having a plurality of second addresses assigned to each according to different assignment policies, and a controller. The plurality of second addresses corresponds to the plurality of first addresses. The second non-volatile memory mirrors data items stored in the first addresses to store them in the second addresses. The controller is configured to receive a command from a host to control the first non-volatile memory and the second non-volatile memory. The controller provides a read command received from the host simultaneously to first and second non-volatile memories, and outputs to the host an earlier one between data provided from the first non-volatile memory and data provided from the second non-volatile memory based on the read command.

    Abstract: An operation method of a storage device, which includes a nonvolatile memory device, includes receiving a first key-value (KV) command including a first key from an external host device; transmitting a first value corresponding to the first key from the nonvolatile memory device to the external host device as first user data, in response to the first KV command; receiving a second KV command including a second key, from the external host device; and performing a first administrative operation based on a second value corresponding to the second key, in response to the second KV command. The first KV command and the second KV command are KV commands of a same type.
