Abstract
An ODT circuit is connected to a memory module and includes a first transmission line, a first ODT, a second ODT, a first switch circuit, a third ODT, a fourth ODT, a second switch circuit, and an ODT control logic. The first and second ODTs are coupled to a first node on the first transmission line. The first switch circuit includes a first switch and a second switch, and is driven according to the first control signal. The third and the fourth ODTs are coupled to a second node on the first transmission line. The second switch circuit includes a third switch and a fourth switch, and is driven according to the second control signal. The ODT control logic outputs the first control signal and the second control signal to control the first switch circuit and the second switch circuit to be turned on at different timings.
