Abstract

Disclosed is an electronic device, including: a switch element; and a memory card slot suitable for receiving a memory card. The memory card slot includes a power supply pin and a detection pin, and the power supply pin of the memory card slot being connected to a power supply through the switch element. The memory card slot has a first configuration where a memory card is received and a second configuration where there is no memory card. In the first configuration of the memory card slot, the detection pin of the memory card slot is in a grounded state, and in the second configuration of the memory card slot, the detection pin of the memory card slot is in a non-grounded state. The detection pin of the memory card slot is connected to the switch element and the detection pin in the grounded state can turn on the switch element.
