    摘要: A phase-changeable layer and a method of forming the same are disclosed. In the method, a first hydrogen gas is introduced into a reaction chamber into which a substrate is loaded at a first flow rate to form first plasma. A primary cyclic CVD process is carried out using precursors in the reaction chamber to form a lower phase-changeable layer having a first grain size on the substrate. A second hydrogen gas is introduced into the reaction chamber at a second flow rate less than the first flow rate to form second plasma. A secondary cyclic CVD process is carried out using the precursors in the reaction chamber to form an upper phase-changeable layer having a second grain size smaller than the first grain size on the substrate, thereby forming a phase-changeable layer. Thus, the phase-changeable layer may have strong adhesion strength with respect to a lower layer and good electrical characteristics.

    摘要: A data output buffer includes a driving unit and a control unit. The driving unit selectively performs a termination operation that provides a termination impedance to a transmission line coupled to an external pin, and a driving operation that provides a drive impedance to the transmission line while outputting read data. The control unit adjusts a value of the termination impedance and a value of the drive impedance based on an output voltage at the external pin during a termination mode, and controls the driving unit to selectively perform one of the termination operation and the driving operation during a driving mode.
