Patent ID: 7729427

Claim:
A method for transferring data between a transmitter and a receiver over a single conductor, comprising the steps of: maintaining the conductor at a first voltage level when data is not being transmitted from the transmitter to the receiver; during a data transfer operation of a bit of information: driving the voltage on the conductor from the first voltage level to a second voltage level to define a first pulse edge of an input signal; maintaining the voltage on the conductor at substantially the second voltage level for a predetermined duration of time, which predetermined duration of time has a length that is determined by the logic state of the data bit; at the end of the predetermined duration of time, allowing the voltage level on the conductor to return to substantially the first voltage level to define a second pulse edge of the input signal; recovering a serial clock signal for each received bit of information responsive to a logic operation of a delayed input signal and an inverted delay of the delayed input signal; and outputting the received data bit responsive to the recovered clock signal associated with the received data bit.
