Summary:A magnetic random access memory (MRAM) using a schottky diode is disclosed. In order to achieve high integration of the memory device, a word line is formed on a semiconductor substrate without using a connection layer and a stacked structure including an MTJ cell, a semiconductor layer and a bit line is formed on the word line, thereby forming the schottky diode between the MTJ cell and the bit line. As a result, a structure of the device is simplified, and the device may be highly integrated due to repeated stacking.
