Semiconductor memory device and method of performing burn-in test on the same

A semiconductor memory device includes a cell array having a plurality of memory cells, each memory cell including a resistive element and a cell transistor between a bit line and a source line, and a source line voltage supply unit configured to supply, in a normal mode, a reference source line voltage to the source line, and in a test mode, a first source line voltage to the source line when data in a first state is recorded and a second source line voltage to the source line when data in a second state is recorded, the first source line voltage being lower than the reference source line voltage, and the second source line voltage being higher than the reference source line voltage.
