Abstract:
A magnetic random access memory comprising:a pair of first word lines formed on a semiconductor substrate; a first impurity junction region and a pair of second impurity junction regions formed on the semiconductor substrate, the first impurity junction region disposed between the pair of first word lines and the pair of second impurity junction regions disposed on both sides of the first impurity junction region so that the pair of first word lines lies on the semiconductor substrate between the first impurity junction region and the pair of second impurity junction regions; a ground line connected to the first impurity junction region; a pair of connection layers respectively connected to the pair of second impurity junction regions; a pair of MTJ cells respectively connected to the pair of connection layers; a pair of bit lines respectively connected to the pair of MTJ cells; a second word line, which is a write line, formed above the ground line to be electrically isolated from the ground line; and a metal wire connected to the second word line, the metal wire running in the perpendicular direction to the pair of bit lines.
