Abstract:
1. A motherboard with reduced power consumption, comprising: a memory module slot for receiving a memory module therein; a DDR (Double data rate) termination array, coupled between the memory module slot and a voltage source, comprising a plurality of termination resistors connected to the voltage source and a plurality of switches between the plurality of termination resistors and the memory module slot, wherein the plurality of switches controlling connections between the memory module slot and the termination resistors are controlled according to a control signal; and a controller chip set, coupled to the memory module slot and the DDR termination array, providing the control signal, wherein when the motherboard enters a power saving mode, or before the memory module is inserted into the memory module slot, the control signal opens the plurality of switches to cut off the coupling between the memory module slot and the termination resistors and thus to cut off the coupling between the slot and the voltage source; and wherein in connection, the plurality of termination resistors are coupled to the memory module in the memory module slot through the plurality of switches.
