Abstract

A magnetic random access memory (MRAM) is disclosed, which achieves high integration by forming second word lines that serve as two write lines for one pair of MRAMs. A contact plug is formed by connecting the second word line to a metal wire formed above the bit lines. As a result, the bit lines and the contact plug are used to drive the device, thereby achieving high integration of the device.
