Abstract
A storage device includes a plurality of nonvolatile memory devices each exchanging data by using a data strobe signal and a data signal, and a storage controller categorizing the plurality of nonvolatile memory devices into a plurality of groups and performing training in units of the plurality of groups. The storage controller performs data training on a first nonvolatile memory device selected in a first group of the plurality of groups and sets a delay of a data signal of a second nonvolatile memory device included in the first group by using a result value of the data training for the first nonvolatile memory device.
