Abstract: A memory device includes a clock receiver configured to receive, from a memory controller, a write clock that is used to receive write data during a data write operation, a duty monitor configured to generate first monitoring information by monitoring a duty of the write clock, and a duty adjuster configured to adjust the duty of the write clock in response to a duty control signal and output an adjusted write clock. The memory device provides the first monitoring information to the memory controller, and receives the duty control signal, generated using the first monitoring information, from the memory controller.

Abstract: A method of operating memory devices disposed in different ranks of a multi-rank memory device and sharing a signal line includes receiving, in all of the memory devices included in the multi-rank memory device, on-die termination (ODT) state information of the signal line. The method further includes storing, in each of the memory devices of the multi-rank memory device, the ODT state information of the signal line in a mode register. The method further includes generating, in each of the memory devices of the multi-rank memory device, a control signal based on the ODT state information of the signal line stored in the mode register. The method further includes changing, in each of the memory devices of the multi-rank memory device, an ODT setting of the signal line in response to the control signal.
