A semiconductor memory module includes a control component connected via various buses to semiconductor memory components on the top and bottom of a module board. Depending on the storage capacity and the rank configuration of the semiconductor memory module, address terminals are actuated via selection circuits either with address signals or control signals. According to an embodiment of the control component, control terminals are actuated with different control signals. The multiplexing of address and control signals allows the control component to control semiconductor memory components, in a semiconductor memory module, with different memory configurations without requiring an increased number of control terminals.
