    摘要: A memory voltage control circuit includes two slots, a control circuit, a voltage conversion circuit, and a switch circuit. The two slots are able to efficiently process different memory types. The control circuit receives memory identification signals from the two slots. The control circuit administers the output voltage of the voltage conversion circuit according to the memory identification signals. The memory identification signals determine whether the switch circuit is to be turned on or off. This will control whether the output voltage of the voltage conversion circuit will go to the first or the second slot.
