3D Racetrack Memory Devices
Funding period: 2025-2028

Magnetic racetrack devices offer distinct potential for achieving both high speed and high-density memory and storage functions. Racetrack is based on the novel concept of moving data, thereby allowing for functionalities not possible with conventional approaches. The group at the MPI-MSP has made significant advances towards practical racetrack devices over the past few years. In Phase 1 the main task is to develop a memory device that is non-volatile with SRAM type performance but requires much less real estate compared to 6T SRAM cells. In further phases, high density memory-storage capabilities will be explored based on both 2D and 3D forms of racetrack.

Within the project, the Dresden Center for Nanoanalysis (DCN) is responsible for the structural, chemical, and magnetic characterization of device elements and devices at the nanoscale as well as for their simulations. The work specifically includes the high-resolution imaging of magnetic domain walls. One focus will be the in-situ magnetic characterization and the correlation between magnetic textures and their underlying local structure and composition.
