Abstract
A method of operating a memory controller includes: receiving a data signal from a memory device, wherein the data signal has an output high level voltage (VOH); determining a reference voltage according to the VOH; and comparing the data signal with the reference voltage to determine a received data value, wherein the VOH is proportional to a power supply voltage (VDDQ).
