A smart card management method, a memory storage device, and a memory control circuit unit are provided. The method includes: receiving a first setting command corresponding to a temporary file from a host system. The temporary file is configured to access the smart card, and the first setting command includes a plurality of first setting messages. One of the first setting messages includes first setting command verification information and first location identification information. The first setting command verification information is configured to verify whether the first setting command is configured to set the temporary file, and the first location identification information is configured to find a logical unit corresponding to the first setting message including the first location identification information. The method also includes: recording a first logic range belonging to the temporary file in a look-up table according to the first setting command.

Smart card management method, memory storage device and memory control circuit unit

A response reading method and a data transmission system are provided. The method includes, transmitting a first operation command sequence corresponding to a first temporary file to a memory storage device by a system, where the first operation command sequence instructs a smart card to execute a first operation. The method also includes, executing a first writing operation of a first dummy file to update first data in a cache memory. The method further includes, executing a response reading operation corresponding to a second temporary file by the system to read a response of the smart card corresponding to the first operation command sequence.

Response reading method and data transmission system

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.
