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.
