Abstract
An On Die Termination (ODT) circuit for performing an ODT operation. The ODT circuit includes a resistor having a first end to receive an ODT enable signal; and a switch unit coupled to a second end of the resistor. The ODT operation is performed in response to the ODT enable signal passing through the resistor.
