Claim 19:
20. A data transmission method, comprising:
controlling a serial-parallel conversion module to receive a plurality of pieces of external data in batches and output initial parallel data according to the external data, wherein a preset bit width of the initial parallel data is equal to a sum of bit widths of the plurality of pieces of external data;
controlling a comparison module to receive global data on a global data line and the initial parallel data, and compare the initial parallel data with the global data to output a comparison result of whether a number of bits of the initial parallel data which are different from the global data exceeds a preset threshold, wherein the initial parallel data and the global data have identical preset bit widths;
controlling a data conversion module to, responsive to that the comparison result indicates that the preset threshold is exceeded, invert the initial parallel data and transmit the inverted data to a data bus, and to, responsive to the comparison result indicates that the preset threshold is not exceeded, transmit the initial parallel data to the data bus; and
controlling a write circuit module to transmit data on the data bus to a global data bus, wherein a length of a data transmission path between the serial-parallel conversion module and the data conversion module is less than a length of a data transmission path between the data conversion module and the write circuit module.
