Abstract
A memory array includes a resistive memory cell array having a first cell transistor and a resistance change element connected in series and a reference cell array having a second cell transistor and a resistance element connected in series. The second cell transistor of the reference cell array is connected to a reference source line, and the resistance element is connected to a reference bit line. A dummy memory cell is connected to the reference bit line in the memory cell array, and both ends of a resistance change element of the dummy memory cell are short-circuited through the reference bit line.
