A system comprises a master device and a plurality of memory devices coupled to the master device by an interconnect in an embodiment. The master device obtains a plurality of values representing reference voltage values and selects a first value in the plurality of values representing reference voltage values to generate an internal reference voltage value when reading data from a selected memory device in the plurality of memory devices. A method comprises obtaining a plurality of values representing reference voltages for a plurality of memory devices in an embodiment. A first value is selected in the plurality of values representing reference voltages. A reference voltage value is adjusted in response to the first value to an adjusted reference voltage value. Data is transferred to a selected memory device in the plurality of memory devices using the adjusted reference voltage value.
