Abstract:
A layout pattern for magnetoresistive random access memory (MRAM) includes a substrate having a first active region, a second active region, and a word line connecting region between the first active region and the second active region, a first gate pattern extending along a first direction from the first active region to the second active region, a second gate pattern extending along the first direction from the first active region to the second active region, a first magnetic tunneling junction (MTJ) between the first gate pattern and the second pattern and within the word line connecting region, and a second MTJ between the first gate pattern and the second gate pattern in the first active region. Preferably, top surfaces of the first MTJ and the second MTJ are coplanar.
