Abstract: A storage device includes at least one nonvolatile memory device and a storage controller. The storage controller controls the at least one nonvolatile memory device based on a request from an external host. The storage controller adaptively adjusts an impedance of a transmission driver based on a change of an operating temperature of the storage device. The transmission driver transmits a transmission signal to the external host through a link. The storage device may increase an eye height of the transmission signal transmitted to the host through the link by decreasing impedance of the transmission driver as the operating temperature increases. Therefore, the storage device according to example embodiments may maintain reliability of the link even though the operating temperature of the storage device increases.
