Material Exploration for Advanced MRAM KU Leuven
Both VCMA and SOT have been demonstrated on imec’s 300mm platform. The issue of field free switching has been overcome through device design and integration e.g. curved SOT lines and integrated hard magnets. However, these limit the scalability of the technology. In addition, the current densities required for SOT are much too large, while the VCMA coefficient is too small limiting its practicality. To solve these issues, we have chosen 3 ...
