Abstract
A memory device includes a data input/output (I/O) pin, an output driver, a multi-level receiver and a calibrator. The output driver is connected to the data I/O pin, and generates an internal input signal based on a first clock signal. The multi-level receiver is connected to the data I/O pin, and includes a plurality of samplers. The plurality of samplers generate a plurality of decision signals by sampling the internal input signal based on a reference voltage and a second clock signal. The calibrator detects and compensates at least one of timing skew and offset associated with the plurality of samplers based on the plurality of decision signals. The internal input signal is a multi-level signal having three or more voltage levels that are different from each other.
