ABSTRACT:
A semiconductor memory device includes a code channel for outputting a plurality of code signals based on a code control signal inputted from an external source; a termination resistor decoder for decoding a chip selection signal, an on die termination (ODT) control signal and the plurality of code signals and outputting a plurality of selection signals based on decoded signals; and an ODT block for providing an output data pad with impedance of a termination resistor which is selected in response to the plurality of selection signals.
