  • Publication number: 20230274771
    Abstract: This application relates to a data transmission circuit, method, and storage devices. The comparison module compares the bus data on the data bus with the global data on the global data line, and the comparison result shows whether the number of bits that are different from the global data on the output bus data exceeds the preset threshold, which is set based on the comparison result. When the comparison result exceeds the preset threshold, a first data conversion module inverts the bus data and provides it to the data bus buffer module, and when the comparison result does not exceed the preset threshold, the bus data is provided to the data bus buffer module. The data bus buffer module generates a data polarity identification signal according to the comparison result, and transmit the bus data or the inverted data of the bus data to the global data line.
