Abstract:
1. A method, comprising: providing at least one conductor for receiving an input signal; coupling a termination circuit to the at least one conductor; coupling a clamp circuit to the at least one conductor; enabling the termination circuit while the clamp circuit remains enabled; disabling the clamp circuit; after disabling the clamp circuit, while the termination circuit remains enabled, enabling both a first differential comparator and a second differential comparator, wherein the first differential comparator receives a first differential input signal at a first input and a second differential input signal at a second input; detecting, by way of the second differential comparator, when a difference between the first differential input signal and the second differential input signal is greater than a predetermined value; and when the difference between the first differential input signal and the second differential input signal is greater than the predetermined value, enabling transfer of an output of the first differential comparator to a memory controller.
