Abstract: A storage device includes nonvolatile memory devices arranged in groups, and a controller connected with the groups respectively through channels. The controller is configured to generate an access request for a nonvolatile memory device among the nonvolatile memory devices, and transmit, based on the access request, access requests respectively to two or more groups, among the groups, respectively through two or more channels, among the channels.

Abstract: Disclosed is a storage device. The storage device includes a nonvolatile memory device that receives write data based on a data strobe signal and a data signal and outputs read data based on the data strobe signal and the data signal, and a controller that performs a training operation for training the nonvolatile memory device to align the data signal and the data strobe signal. The controller detects a left edge of a window of the data signal for the training operation. The controller determines a center of the window by using the detected left edge and unit interval length information of the data signal or determines a start point of a detection operation for detecting a right edge of the window by using the detected left edge and the unit interval length information.
