ABSTRACT:
An on-die termination circuit with a stable effective termination resistance value and stabilized impedance mismatching. The on-die termination circuit includes: a decoding unit for decoding set values of an extended mode register set; an ODT output driver block including a plurality of output driver units connected in parallel with an output node for outputting an output signal and assigned with different resistance values; and a control signal generation block for generating a plurality of pull up and pull down control signals for turning on/off the plurality of output driver units in response to output signals of the decoding unit.
