  • Method and apparatus for buffering an input-output node of an integrated circuit
    Patent number: 6366129
    Abstract: An input-output (I-O) buffer for an integrated circuit. The buffer includes a controller and first and second groups of transistors to pull the node up and down, respectively. The controller is configured to turn on a transistor from the first group to drive a high bit on the node during a first period of time. The controller is further configured to turn on transistors from both the first and second groups, simultaneously, to terminate the node during a second period of time.

  • Method and apparatus for controlling impedance on an input-output node of an integrated circuit
    Patent number: 6232814
    Abstract: An input-output (I-O) buffer for an I-O node of an integrated circuit. The buffer includes a group of transistors to pull the node up. A shift register has each of two or more of its storage cells coupled to a gate of each of the transistors to control the impedance of the buffer.
