Abstract: A memory device includes a base die configured to transmit transmission data that are driven to a first voltage range through a transmission line based on base data, and a core die configured to generate core data by shifting a voltage level of the transmission data received through the transmission line to a second voltage range.

Abstract: Provided is a print device including a body forming an appearance, a coupling unit formed in the body to enable physical coupling to an auxiliary device, a recognition unit formed in the body to recognize the auxiliary device and determine whether the coupling unit is coupled to the auxiliary device, and a control unit. When the recognition unit recognizes that the auxiliary device is not coupled to the coupling unit, the control unit sets the auxiliary device to perform a basic function, and when the recognition unit recognizes that the auxiliary device is coupled to the coupling unit, the control unit sets the coupled auxiliary device to perform an individual function changed from the basic function.
