    Abstract: PROBLEM TO BE SOLVED: To provide reading to and writing from peripherals by using the execution of a temporally separated redundant processor with high safety. SOLUTION: A first processor reads data from a peripheral device and copies the data to a register. A reading attempt from the peripheral by a temporally separated second processor is bypassed to the register, and the data is read from the register. Thereby sameness of the read data is guaranteed. Embodiments can be utilized in safety-relevant applications related to automotive, banking and finance, aerospace, defense, Internet payment, and others. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a method and system for creating/updating a backup volume based on a host volume. SOLUTION: A backup volume on a backup system is created/updated by reading data stored on a host volume on a host system. A data profile for the host volume is generated based on the read data, where the data profile characterizes the data stored on the host volume. The data profile is sent to the backup system, and data that does not need to be obtained from the host system is determined on the backup system based on the data profile. COPYRIGHT: (C)2004,JPO

    Abstract: PROBLEM TO BE SOLVED: To provide a test result which is sure and trackable, in a method for testing a semiconductor chip, especially, a semiconductor memory chip. SOLUTION: In a method for testing a semiconductor chip, especially, a semiconductor memory chip, at least one test mode is set in a chip to be tested, the test mode is performed in the chip, the test result is outputted from the chip. After setting the test mode, and before performing the test mode, a verification mode is performed, and in the test mode, a state of the test mode set in the chip is read with the prescribed format.
