ABSTRACT:
The present invention discloses an on die termination circuit. The on die termination circuit used in a DDR2 employs transmission gates as pull-up and pull-down switches, equalizes pull-up and pull-down resistance values by changing connection relations between switches and resistors, and maintains a constant voltage of an input pin.
