Abstract: The disclosure provides a restart control device and a restart control method. The restart control device is disposed in an electronic device. The electronic device includes a keyboard and a restart button. At least one assigned key of a plurality of keys of the keyboard is set. The restart control device determines whether the at least one assigned key is pressed, and determines whether the restart button is pressed. When determining that the restart button is pressed and the at least one assigned key is pressed, the restart control device provides a restart control signal to cause the electronic device to perform a restart operation. The disclosure can prevent an unnecessary restart operation due to a single restart button being mistyped.

Abstract: An electronic apparatus and a method for detecting status of keys thereof are provided. The electronic apparatus comprises a key module, a key control circuit, a conversion circuit with calibration mechanism and a processor. The key control circuit detects whether any of keys in the key module is pressed. If the detection result is affirmative, the press status of each of the keys is scanned by the key control circuit to obtain a coarse scan result. The conversion circuit with calibration mechanism is configured to perform the other system function of the electronic apparatus. When the processor determines that at least one of the keys is not pressed according the coarse scan result, the conversion circuit with calibration mechanism is switched to assist a re-scan operation of the press status of the at least one of the keys.

Abstract: A flash memory storage system includes a flash memory, a host and a controller is provided. The controller couples to the host and the flash memory, and restricts the host to access the flash memory according to a state of the host. When the host is in a booting state or in a resetting state, the controller allows the host to access the flash memory. After the host completes a booting process or a resetting process, the controller restricts the host to access the flash memory so as to protect a data stored by the flash memory. Besides, a data protection method for which applied to the above-mentioned storage system is also provided in the present invention.

Abstract: An integrated memory control apparatus including a first interface decoder, a second interface decoder and an interface controller is provided. Wherein, the first interface decoder is coupled to a control chip through a first serial peripheral interface (SPI), the second interface decoder is coupled to a micro-processor unit through a general transmission interface, and the interface controller is coupled to a memory through a second SPI. When the interface controller receives the request signals from the control chip and the micro-processor unit, the control chip may correctly read data from the memory through the first and second SPI. On the other hand, the micro-processor unit may stop reading data from the memory through the general transmission interface. Therefore, the control chip and the micro-processor unit may share the same memory.

Abstract: A data access method for serial bus is provided. During a write/read cycle, the write/read cycle is divided into a plurality of transmitting intervals and a plurality of suspending intervals. In each of the transmitting intervals, a clock signal is transmitted on a clock pin and a data signal is transmitted on a data pin.

Therefore, the present invention can decrease the cost of the embedded controller and reduce the area of the integrated circuit.
