Abstract

A method of calibrating a signal level of a memory device includes performing pull-up code and pull-down code calibrations, using a ZQ calibration for non-return-to-zero (NRZ) signaling, performing a most significant bit (MSB) code calibration, using an MSB additional driver for pulse amplitude modulation level-4 (PAM4) signaling, and performing a least significant bit (LSB) code calibration using an LSB additional driver for the PAM4 signaling.
