    Abstract: A data storage device is provided. The data storage device includes: a first function block of a device controller configured to receive user data and perform a first data processing; a first buffer memory connected to the first function block and configured to store user data subjected to the first data processing as first process data; a second function block of the device controller configured to receive a data write command determined based on the first process data; and a non-volatile memory connected to the second function block, and configured to receive and store data stored in the first buffer memory. The user data is provided to the first function block before the data write command is provided to the second function block.

    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.

    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.
