Abstract:
A method of buffering data from core circuitry includes generating a first sourcing control signal responsive to indication signals indicating an operating voltage and output data, generating a second sourcing control signal responsive to the indication signals, and applying the operating voltage to an output terminal in response to the first sourcing control signal and the second sourcing control signal. The first sourcing control signal swings between the operating voltage and a reference voltage. The reference voltage is a signal selected from among a plurality of internal voltages in response to selection signals generated as a result of decoding the indication signals.
