description A memory card with a smart card function including a flash memory unit, a data processing control unit, and a power control unit is provided. The data processing control unit is coupled to the flash memory unit. The data processing control unit controls the flash memory unit and encrypts, decrypts and stores smart card security data. The power control unit receives at least one of a first power input and a second power input. The power control unit selects the first power input or the second power input and provides the selected one to the data processing control unit according to at least one control signal. An output terminal of the power control unit is coupled to the first power input. Furthermore, a power control method and a power control circuit of the forgoing memory card are also provided.
