Abstract

A semiconductor device includes a magnetic random access memory (MRAM) cell. The MRAM cell includes a first magnetic layer disposed over a substrate, a first non-magnetic material layer made of a non-magnetic material and disposed over the first magnetic layer, a second magnetic layer disposed over the first non-magnetic material layer, and a second non-magnetic material layer disposed over the second magnetic layer. The second magnetic layer includes a plurality of magnetic material pieces separated from each other.
