Abstract
A memory module is provided with a resistor serving as an impedance adjuster which is connected directly or indirectly to an output terminal of an output transistor of a C/A register. The resistor adjusts the output impedance of the C/A register viewed from an input terminal of a C/A bus in such a manner that the output impedance becomes substantially constant within an operating voltage range of an internal signal output from the C/A register. The memory module is further provided with a capacitor serving as a rise time/fall time adjuster which adjusts rise time and fall time of the internal signal to specific values such that satisfactory waveforms are obtained.
