  • Patent number: 10666235
    Abstract: A temperature compensated oscillation circuit is provided. The temperature compensated oscillation circuit generates a first delay voltage and a second delay voltage according to the first resistance value. A first order term of a temperature change function of the first resistance value is eliminated. The temperature compensated oscillation circuit generates a reference voltage according to a first reference resistance value and a second reference resistance value. A first order term of a temperature change function of the first reference resistance value is set to equal to a first order term of a temperature change function of the second reference resistance value. The second reference resistance value is adjusted such that variation of the reference voltage matches a second order term of the temperature change function of the first resistance value, thereby providing a clock that does not vary due to a variation in temperature.

  • Patent number: 10289211
    Abstract: A keyboard apparatus and a detection method for status of keys thereof are provided. The detection method includes the following steps. First lines of a key module in the keyboard apparatus are driven to a first potential. Whether any key on each of second lines in the key module is pressed is detected as a first detection result. The second lines are driven to the first potential. Whether any key on each of the first lines is pressed is detected as a second detection result. One of the first lines is sequentially selected, and a press status of each key on the selected first line is scanned through the second lines so as to generate a coarse scan result. The press status of each key is obtained and whether the press status is misjudged is determined according to the first and the second detection results and the coarse scan result.

  • Publication number: 20130151832
    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.
