A segmented group inversion encoding method for parallel data transmission is provided to minimize a switching noise in single ended parallel data transmission by performing inversion encoding of the group. A segmented group inversion encoding method for parallel data transmission includes the steps of: initializing all flag bits to a specific value when the k number of data groups transmitted from a transmission terminal to a receiving terminal are included, and one data group of the transmitted data groups includes data bit and the other groups of the transmitted data groups include the data bit and the flag bit; outputting original data of the one data group having the data bit only through corresponding pins without encoding; and if the data group includes first to k-th groups, and the one data group having the data bit only is the k-th group, performing inversion encoding of the i-th group according to a number difference of zero and one of the i-th group, and a number difference of total zero and one of the encoded i+1th to k-1th groups and k-th group.
