20120056665 | INPUT/OUTPUT CIRCUIT WITH HIGH VOLTAGE TOLERANCE AND ASSOCIATED APPARATUS - An input/output (IO) circuit with high voltage tolerance is provided. In an integrated circuit, the IO circuit includes a charge pump for generating a bias voltage higher than an internal operating voltage of the charge pump itself, and a switch between an external circuit and an internal circuit of the integrated circuit. When the switch conducts between the external circuit and the internal circuit, the switch provides a clamping voltage according to the bias voltage and a cross voltage of the switch, so that a voltage of the internal circuit is bounded by the clamping voltage to prevent the internal circuit from over-voltage. | 03-08-2012 |

20100074071 | METHOD FOR READING DISK MANAGEMENT DATA OF AN OPTICAL DISK - The invention provides a method for reading disk management data of an optical disk. In one embodiment, the disk management data comprises data layout information of the optical disk, and a plurality of disk management data copies of the disk management data is stored on the optical disk. First, a first disk management data copy selected from the plurality of disk management data copies is read from the optical disk. An accuracy measure of the first disk management data copy is then calculated to determine whether the accuracy measure of the first disk management data copy is acceptable. When the accuracy measure of the first disk management data copy is acceptable, the optical disk is accessed according to the first disk management data copy. | 03-25-2010 |
