Abstract: A storage device includes a nonvolatile memory device, and a controller that exchanges a data signal with the nonvolatile memory device through a data input and output line and exchanges a data strobe signal with the nonvolatile memory device through a data strobe line. In a training operation, at least one of the nonvolatile memory device and the controller performs a coarse training of adjusting a delay of the data signal with a first stride and a fine training of adjusting the delay of the data signal with a second stride smaller than the first stride.

Abstract: A storage device including a nonvolatile memory device including memory blocks and a controller connected with the nonvolatile memory device through data input and output lines and a data strobe line may be provided. The nonvolatile memory device and the controller may be configured to perform training on the data input and output lines by adjusting a delay of a data strobe signal sent through the data strobe line and adjust delays of the data input and output lines based on the training result.
