Abstract
Methods and apparatus for shielding a shielding a non-volatile memory, such as shielding a magnetic tunnel junction (MTJ) device from a magnetic flux are provided. In an example, a shielding layer is formed adjacent to an electrode of an MTJ device, such that the shielding layer substantially surrounds a surface of the electrode, and a metal line is coupled to the shielding layer. The metal line can be coupled to the shielding layer by a via.
