More Information
Summary:A memory device includes a first termination unit coupled to a first pin for receiving a first signal having a first frequency component. The memory device also includes a second termination unit coupled to a second pin for receiving a second signal having a second frequency component higher than the first frequency component. The first termination unit is a different type from the second termination unit that provides less signal distortion than the first termination unit. For example, the first termination unit is of an open-drain type that has less power consumption, and the second termination unit is of a push-pull type that has less signal distortion.
