主权项 1. A memory comprising: an array of perpendicular spin-transfer torque (STT) magnetic random access memory (MRAM) cells, wherein each cell has a magnetic layer stack; a magnetic shield disposed between the cells and having a minimum height of at least the height of the magnetic layer stacks to thereby shield the cells from memory-external magnetic fields; and an isolation layer disposed directly on the magnetic shield and a top electrode.
