Claim 13:
14. A data transmission method, comprising:
comparing first data on a data bus with second data on a global data line, and outputting a comparison result of whether a number of different bits between the first data and the second data exceeds a preset threshold, wherein the first data and the second data have a same preset bit width;
in response to the comparison result indicating that the number of different bits exceeds the preset threshold, inverting the first data and transmitting the inverted first data to the global data line; in response to the comparison result indicating that the number of different bits does not exceed the preset threshold, transmitting the first data to the global data line; and
in response to the comparison result indicating that the number of different bits exceeds the preset threshold, transmitting data on the global data line to a complementary local data line; and in response to the comparison result indicating that the number of different bits does not exceed the preset threshold, transmitting data on the global data line to a local data line, wherein the local data line transmits a signal having a phase which is opposite to a phase of a signal transmitted by the complementary local data line.
