Abstract

A semiconductor device includes a substrate having a logic region and a magnetoresistive random access memory (MRAM) region, a MTJ on the MRAM region, a metal interconnection on the MTJ, and a blocking layer on the metal interconnection. Preferably, the blocking layer includes a stripe pattern according to a top view and the blocking layer could include metal or a dielectric layer.
