A storage device includes a nonvolatile memory device and a controller configured to read data from the nonvolatile memory device, to divide the read data into a plurality of segments, and to sequentially perform error correction decoding with respect to the plurality of segments. When the error correction decoding of each segment is completed, the controller adds error correction parity to each of the decoded segments and sends the decoded segments with added error correction parity to an external host device. When error correction decoding of a second segment is not completed after a threshold time has elapsed after sending a first segment of which error correction decoding is completed, the controller adds an incorrect error correction parity to dummy data and sends the dummy data with the added incorrect error correction parity to the external host device.

Storage device and operating method of storage device

A host system includes a host device, a host buffer memory, and storage device. The host device includes a plurality of cores. The host buffer memory is configured to store a first command queue and a first map table, wherein each of the first command queue and the first map table corresponds to a first core of the cores. The storage device is configured to perform an input/output virtualization operation using the first core as a virtual core. The storage device uses the first command queue and the first map table during the input/output virtualization operation using the first core.

Storage device, a host system including the storage device, and a map table updating method of the host system

A storage device includes a plurality of nonvolatile memories; and a storage controller which is connected to the nonvolatile memories and controls the nonvolatile memories, wherein the storage controller is configured to, perform an interface operation on the basis of a queue-based command exchange scheme with a host, and access administrator queue information corresponding to each of a plurality of virtualization functions of the host.
