Abstract: A memory system includes a nonvolatile memory module and a first controller configured to control the nonvolatile memory module. The nonvolatile memory module includes a volatile memory device, a nonvolatile memory device, and a second controller configured to control the volatile memory device and the nonvolatile memory device. The first controller may be configured to transmit a read request to the second controller. When, during a read operation according to the read request, normal data is not received from the nonvolatile memory device, the first controller may perform one or more retransmits of the read request to the second controller without a limitation on a number of times that the first controller performs the one or more retransmits of the read request.

Abstract: A training method of a memory device adjusting an eye window of a data signal in response to a duty cycle adjuster (DCA) includes performing a first training operation that selects a first DCA code corresponding to a first internal clock signal having a phase difference of 180° relative to a reference internal clock signal, and performing a second training operation that selects a second DCA code and a third DCA code respectively corresponding to a second internal clock signal and a third internal clock signal having a phase difference of 90° and 270° relative to reference internal clock signal. In the first training operation, the eye window size of the data signal is measured in units of two unit intervals, and in the second training operation, the eye window size of the data signal is measured in units of one unit interval.

Abstract: A method of training a memory device is provided. In first to third DCA training steps, a score for each of first to third DCA code combinations is calculated based on an eye window size of a data signal, and in response to a tie occurring among scores, a DCA code combination is selected based on the sum of an even-eye window minimum value and an odd-eye window minimum value of the data signal.

Abstract: Provided are a memory device skipping a refresh operation and an operating method thereof. The memory device includes a memory cell array including N rows; a refresh controller configured to control a refresh operation for the N rows of the memory cell array based on a refresh command; and an access information storage circuit including a plurality of registers configured to store flag information corresponding to each of the N rows, wherein a first value indicates rows that have been accessed, and a second value indicates rows that have not been accessed. The refresh controller is further configured to control whether the refresh operation is performed for a first row of the N rows at a refresh timing for the first row based on the flag information corresponding to the first row
