Abstract
An apparatus is described that includes a memory channel driver circuit having first driver circuitry to drive a data signal on a memory channel and second driver circuitry to drive an echo cancellation signal on the memory channel. The echo cancellation signal includes echo cancellation pulses that follow corresponding pulses of the data signal by an amount of time that causes the echo cancellation pulses to reduce reflections of the corresponding pulses of the data signal at a memory device that is coupled to the memory channel.
