Abstract: A storage device comprising a nonvolatile memory device, and a storage controller configured to control the nonvolatile memory device wherein the storage controller is configured to, detect a logical address pattern repeatedly requested by a host, divide the logical address pattern into input logical addresses and predictive logical addresses, and generate a reproduction model for generating reproduction data corresponding to the predictive logical addresses in the data pattern when the predictive logical addresses are input using machine learning, and in response to a read request for the input logical addresses from the host, predict the predictive logical addresses using the input logical addresses, generate the reproduction data by inputting the predictive logical addresses into the reproduction model, and prefetch the generated reproduction data to a buffer memory included in the storage controller.
