Abstract
A multi-level signal generator includes a receiving circuit, a setting circuit, a data bit generating circuit and a digital-to-analog converter. The receiving circuit generates a first data bit based on an input data signal having two voltage levels that are different from each other. The setting circuit generates a flag signal based on a command signal. The flag signal is changed depending on an operation mode. The data bit generating circuit generates a plurality of internal bits based on the first data bit, selects at least one of the plurality of internal bits based on the flag signal, and outputs the selected internal bit as at least one additional data bit. The digital-to-analog converter generates an output data signal that is a multi-level signal having three or more voltage levels different from each other based on the first data bit and the at least one additional data bit.
