Abstract
A memory device includes a memory cell array and a transmitter, wherein the transmitter includes a pulse amplitude modulation (PAM) encoder configured to generate a PAM-n first input signal (where n is an integer greater than or equal to 4) from data read from the memory cell array; a pre-driver configured to generate a second input signal based on the first input signal and based on a calibration code signal, and output the second input signal using a first power voltage; and a driver configured to output a PAM-n DQ signal using a second power voltage lower than the first power voltage in response to the second input signal.
