A buffer includes a pull-down means, a pull-up means, and a control signal generator. The pull-down means generates an output signal that transitions to a first state at a relatively high speed when an input signal transitions from a first state to a second state in response to a control signal at a first control state. The pull-up means generates an output signal that transitions to the second state at a relatively high speed when an input signal transitions from the second state to the first state in response to a control signal of a second control state. The control signal generator produces the control signal as a function of the output signal. Accordingly, the buffer can transfer an input signal at a high speed in both cases of a high-to-low transition of the input signal as well as a low-to-high transition of the input signal.
