Abstract
Integrated circuit memory devices include one or more input receivers that have a reference voltage input terminal. A conductor electrically couples the reference voltage input terminals to a reference voltage, and a capacitor is connected between the conductor and a first ground voltage. Preferably, the location of the connection between the capacitor and the conductor is selected in accordance with the electrical characteristics of the input receivers. Accordingly, the capacitor may reduce fluctuations or noise in the reference voltage applied to the reference voltage input terminals of the input receivers. The fluctuations or noise in the reference voltage may cause the input characteristics and/or the set-up and hold times of the input receivers to vary with respect to one another. A reduction in fluctuations or noise in the reference voltage may result in more consistent input characteristics among the input receivers and more consistency in the set-up and hold times.
