Abstract: A method of state maintenance for a MMC system. The method includes using a plurality of signals, including a working voltage signal, a low voltage detection (LVD) signal, an LVD interrupt signal, a firmware polling signal, an LVD interrupt reset signal. The LVD signal responds to a voltage level of the working voltage at a preset voltage level. The LVD interrupt signal responds to the level of the LVD signal. After the LVD signal returns to the high level state and the firmware polling signal does the polling action to the LVD interrupt signal, then the LVD interrupt reset signal is issued to reset the LVD interrupt signal.

Abstract: A memory driving circuit has a register for receiving a new-coming data and a delayed clock, and exporting a current-existing data. The delayed clock has a delay to a clock. A pre-detecting circuit receives the current-existing data, the new-coming data, and a pre-enable signal, and exports an output signal. Wherein, the current-existing data is compared with the new-coming data. The output signal indicates a disable state if the two data are the same. Otherwise, the output signal indicates an enable state, wherein the pre-enable signal is also used to enable or disable the pre-detecting circuit. An output driving circuit receives the current-existing data and an enabling signal, and exports a first output signal. A pre-driving circuit receives the output signal of the pre-detecting circuit and an enable control signal, and exports a second output signal. An I/O pad receives the first output signal and the second output signal.

Abstract: A memory storage device includes a host interface to be connected to a terminal host, a controller connected to the host interface, and a fingerprint sensor and a memory module both connected to the controller. The controller communicates with the terminal host by handshakes and causes the terminal host to automatically run a suitable driver and a suitable application program from the memory module to the terminal host. The terminal host receives an instruction from a user through the driver and the program and informs the controller to control the fingerprint sensor to read to-be-recognized fingerprint data of the user. The terminal host utilizes the application program to process and judge whether or not the to-be-recognized fingerprint data substantially matches with template fingerprint data stored in the memory module, and further enables a specific block of the memory module to be accessed by the terminal host according to a matching result.
