Patent ID: 7337250

Claim:
A data transmission device comprising: a transmitter for transmitting a data word from a host, the transmitter including: a plurality of data transmission devices, each for receiving a data bit of the data word from the host and transmitting the data bit to a data bus; and a first logic device which outputs a first signal to the data bus when the data word from the host is input to the transmitter for transmission; and a receiver for receiving the data word from the transmitter, the receiver including: a plurality of data reception devices, each for receiving a data bit of the data word from a corresponding data transmission device over the data bus; and a first register for receiving the first signal associated with the data word from the first logic device and inputting the first signal to each of the plurality of data reception devices to instruct the plurality of data reception devices to sample the data bit transmitted from the corresponding data transmission device; wherein the first signal associated with the data word is transmitted from the first logic device to the first register before the data bits of the data word are transmitted from each of the plurality of transmission devices to the corresponding plurality of reception devices; and wherein the first register inputs the first signal to each of the plurality of data reception devices substantially simultaneously with the transmission of the data bit from each of the plurality of transmission devices to the corresponding reception device over the data bus.
