Abstract:
A bi-directional buffer is provided. The buffer includes a driver, a receiver, and a circuitry configured to select a driving mode in response to detecting a first condition and to select a receiving mode in response to detecting a second condition. The driving mode has a first impedance and the receiving mode has a second impedance. The second impedance is partially contributed from the driver.
