Abstract
A MRAM memory and process thereof is described. A GMR magnetic layer is patterned to form a memory bit layer and an intermediate conductive layer. The intermediate conductive layer is disposed between two conductive layers such that shallow metal plugs can be utilized to interconnect the intermediate conductive layer and the conductive layers. Thus, a conventional deep tungsten plug process, interconnecting two conductive layers, is eliminated.
