Abstract
A memory device is connected through an interface to a memory controller. The memory device's reference voltage is set based on a driver's impedance of the memory device and the controller driver drive strength during driver training. The voltage is applied to a reference resistor pair at the memory device and changed until the voltage level switches. The voltage is then set at the reference resistor pair of the memory device.
