<p>An electronic device capable of switching between sleep mode and working mode is provided. The electronic device includes a volatile memory device and a power switching device. The volatile memory device is coupled to the power switching device, and receives power through the power switching device. The power switching device is configured to couple the volatile memory device to a local power supply when the electronic device is in working mode such that the volatile memory device is powered by the local power supply, and couple the volatile memory device to a network power supply when the electronic device is in sleep mode such that the volatile memory device is powered by the network power supply. There is no need for the electronic device to have a switching power supply to power its volatile memory device under sleep mode, which saves more power.</p> |
