A memory and a voltage monitoring device thereof are provided. the voltage monitoring device of the memory includes a system voltage detector, a charge pump circuit and a data output unit. The system voltage detector is coupled to the charge pump circuit and the data output unit for detecting a system voltage and thereby producing control signals. The charge pump circuit can produce a word line voltage according to the above-mentioned control signals. The data output unit decides outputting the above-mentioned control signals or the output data of the memory according to a special command, wherein the control signals correspond to the word line voltages. Therefore, the control signals and the word line voltages may be easily monitored.
