<p>An on die termination (ODT) control device includes a latency block for buffering an ODT control signal to output a latency control signal by selecting one of a plurality of intermediate control signals, which are generated by sequentially delaying the buffered ODT control signal in synchronization with an internal clock, based on first latency information; an enable signal generation block for comparing a first control signal with a second control signal in response to the latency control signal to thereby produce an ODT enable signal based on the compared result; and an ODT block for controlling a termination impedance based on the ODT enable signal.</p> |
