The Magnetic Random Access Memories (MRAM) group develops advanced concepts in this emerging technology. The goal is to realize cells with improved thermal stability, lower power consumption and/or faster switching. Our research covers material stack deposition, nano-fabrication and electrical test evaluation, for applications as standalone memory and non-volatile logic.
Perpendicular Anisotropy Materials
High energy barriers for spin transfer torque (STT) MRAM cells can be achieved with perpendicular anisotropy magnetic tunnel junctions. Solutions for high density MRAM cells to diameters below 20nm require continuous improvements in perpendicular surface anisotropy, while maintaining high TMR properties.
Perpendicular STT MRAM
Evaluation of MRAM concepts requires simulation of expected reversal mechanisms and electrical characterization of individual cells. We aim at understanding dynamics of magnetization reversal and the expected impact of stack modifications to explore application specific optimizations.
CMOS Integration for Non-Volatile Logic
The challenge to validate hybrid CMOS designs to create non-volatile logic circuits requires the backend integration of MRAM cells with custom CMOS circuits. Our goal is to provide an integration platform for proof-of-concept prototype runs.
Thermally Assisted Switching
Perpendicular anisotropy magnetic tunnel junctions provide a solution to for high density MRAM cells where the cell diameter can be scaled to 20nm and possibly below. Thermal assisted STT writing in perpendicular cells allows large values of thermal stability, while maintaining a low critical current via the thermal re-orientation of perpendicular anisotropy storage layers.
