摘要： 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.
