1. A method of transferring read data from a memory device, the memory device including a data bus and including at least one data masking pin adapted to receive a data masking signal during write operations of the memory, the method comprising: placing a current read data word on the data bus, the read data word including a plurality of data signals and each data signal having a logic state; developing a next read data word, the next read data word including a plurality of data signals and each data signal having a logic state; comparing the logic state of each data signal in the current read data word to the logic state of the corresponding data signal in the next read data word; determining the number of data signals in the next read data word that are changing from a first logic state in the current read data word to the complementary logic state in the next read data word; when the determined number of data signals changing from the first logic state to the complementary logic state is greater than N, developing an inverted next read data word, each data signal in the inverted next read data word having a logic state that is the complementary logic state of the corresponding data signal in the next read data word, and activating a data bus inversion signal; placing the inverted next read data word on the data bus; and applying the activated data bus inversion signal on one of the data masking pins.
