Serial advanced technology attachment dual in-line memory module device

A serial advanced technology attachment dual in-line memory module (SATA DIMM) device, comprising:

• a first electronic switch comprising first to third terminals;
• a second electronic switch comprising first to third terminals;
• a voltage detecting circuit comprising an input terminal, and an output terminal connected to the first terminals of the first and second electronic switches;
• a power circuit connected to the third terminals of the first and second electronic switches;
• and
• an edge connector comprising:
• a plurality of first power pins connected to the input terminal of the voltage detecting circuit;
• a plurality of second power pins connected to the second terminal of the first electronic switch;
• a plurality of third power pins connected to a second terminal of the second electronic switch, wherein the plurality of third power pins is located between the plurality of first power pins and the plurality of second power pins;
• a first notch arranged on the edge connector and located between the first and third power pins;
• and
• a second notch arranged on the edge connector and located between the second and third power pins;
• wherein when the edge connector is connected to a double data rate type two (DDR2) memory slot, the second notch receives a protrusion of the DDR2 memory slot, the voltage detecting circuit gains a first voltage through the first power pins and outputs a first control signal according to the first voltage for controlling the first electronic switch to be turned on, the second electronic switch is turned off, the voltage detecting circuit provides the first voltage to the power circuit through the first electronic switch and the second power pins provide a second voltage received from a motherboard mountable with the DDR2 memory slot to the power circuit through the first electronic switch;
• and
• wherein when the edge connector is connected to a double data rate type three (DDR3) memory slot of the motherboard, the first notch receives a protrusion of the DDR3 memory slot, the voltage detecting circuit gains a third voltage through the first power pins and outputs a second control signal according to the third voltage for controlling the first electronic switch to be turned off, the second electronic switch is turned on, the voltage detecting circuit provides the third voltage to the power circuit through the second electronic switch and the third power pins provides a fourth voltage received from the motherboard to the power circuit through the second electronic switch.
