Abstract:
A memory module includes an external resistor and a plurality of memory devices commonly connected to the external resistor. Each of the memory devices includes a first reception pad and a first transmission pad. The first reception pad is associated with receiving an impedance calibration command and the first transmission pad is associated with transmitting the impedance calibration command. Each of the memory devices transfers the impedance calibration command to a first memory device which is selected as a master among the plurality of memory devices through a ring topology. The first memory device performs an impedance calibration operation, determines a resistance and a target output high level voltage of an output driver in response to the impedance calibration command, and transfers the impedance calibration command to a second memory device after performing the impedance calibration operation.

Claim (Index 3):
The memory module of  claim 1 , wherein each of the plurality of memory devices further comprises:\n an impedance pad connected to the external resistor; and an impedance calibration circuit connected to the first reception pad, the first transmission pad, the impedance pad, and the selection pad, wherein the impedance calibration circuit comprises: a detector connected to the selection pad, and configured to generate a detection signal; a command controller connected to the first reception pad and the first transmission pad, wherein the command controller is configured to receive the impedance calibration command from one of the first reception pad and a corresponding command decoder; and a calibration circuit connected to the external resistor through the impedance pad, wherein the calibration circuit is configured to perform the impedance calibration operation in response to a calibration enable signal from the command controller to output a pull-up control code and a pull-down control code to the output driver, and is configured to provide the command controller with a first comparison signal and a second comparison signal which indicate a completion of the impedance calibration operation.
