Access apparatus of memory card and control method thereof

A control method for an access apparatus of memory card, wherein the access apparatus is adapted for receiving a memory card with a side having a supply voltage pin, the control method comprising:

• providing a slot module, wherein the slot module having a slot to receive insertion of the memory card, the slot comprises a first side and a second side corresponding to each other, the first side and the second side are respectively configured with a first supply voltage pin and a second supply voltage pin, and the first supply voltage pin and the second supply voltage pin are spaced apart and opposite to each other;
• conducting the supply voltage pin with the first supply voltage pin of the slot when the memory card is inserted into the slot module with a first facing direction, such that a write operation is able to be performed to the memory card;
• and
• conducting the supply voltage pin with the second supply voltage pin of the slot when the memory card is inserted into the slot module with a second facing direction, such that the write operation is forbidden to be performed to the memory card.
