    摘要: A data line termination circuit includes a swing-width sensing unit configured to sense a swing width of a voltage of a data line and output a sensed signal, and a variable termination unit configured to adjust a termination resistance value of the data line in response to the sensed signal. The swing-width sensing unit can sense if the swing width is less than or greater than a predetermined swing width, and the swing width of the voltage of the data line can be reduced or increased to maintain the voltage of the data line within a predetermined range.
