A method for transmitting a command signal and an address signal to a rank which is to be accessed includes receiving and buffering the command signal and the address signal, and transmitting the buffered command signal and address signal to the rank, in response to a clock signal and a select signal for accessing rank. Transmitting the buffered command signal and address signal to the rank includes latching the buffered command signal and address signal, in response to the select signal, and transmitting the latched command signal and address signal to the rank, in response to the clock signal. The method and an associated apparatus can selectively transmit a command signal and an address signal to a rank or plurality of memory devices in a memory module, thereby reducing the amount of current consumed by memory modules that are not to be accessed.
