  • Patent number: 11561872
    Abstract: A database system includes a master server, a pair of slave servers and a main storage carrier. Each slave server is provided with a database management system (DBMS). The main storage carrier and the pair of slave servers uses the ISCSI protocol to make the pair of slave servers serving as the DBMS and the main storage carrier serving as a database (DB) connect and communicate to further make the DBMS and the DB independent and separate. The master server performs service assignment to the pair of slave servers according to a predetermined weight value. All connections of the database are directed to the slave server with a high weight value, and the other slave server with a low weight value serves as a standby.

  • Patent number: 11550710
    Abstract: A memory controller includes a memory interface and a processor. The processor is coupled to the memory interface and controls access operation of a memory device via the memory interface. The processor maintains a predetermined table according to write operation of a first memory block of the memory device and performs data protection in response to the write operation. When performing the data protection, the processor determines whether memory space damage has occurred in the first memory block. When it is determined that memory space damage has occurred in the first memory block, the processor traces back one or more data sources of data written in the first memory block according to the predetermined table to obtain address information of one or more source memory blocks and performs a data recovery operation according to the address information of the one or more source memory blocks.

  • Patent number: 11543455
    Abstract: A circuit measuring device and a method thereof are provided. A voltage source supplies a common voltage such that a calibration current having a preset current value flows from a current-voltage converter to a final test machine. The current-voltage converter converts the calibration current into a calibration voltage. At this time, a voltage sensing component senses a voltage between an input terminal and an output terminal of the current-voltage converter to output sensed calibration data. The current-voltage converter converts a tested current outputted by a tested circuit into a tested voltage. At this time, the voltage sensing component senses the voltage between the input terminal and the output terminal of the current-voltage converter to output actual sensed data. When the final test machine determines that a difference between the sensed calibration data and the actual sensed data is larger than a threshold, the tested circuit is adjusted.
