FROM TECHNOLOGY MODULES TO DEVICES AND NEW CIRCUIT ARCHITECTURES
Leti innovates in various fields of data storage technologies: silicon based, resistive memories, magnetoresistive memories, superresolution optical discs etc.
Leti has helped its industrial partners address multiple needs:
- CVD tool development for the deposition of phase change materials,
- optimization of materials for embedded phase change memories,
- transfer of technology modules in silicon based memories
Leti investigates mainly two technologies
- “charge-trap” memories, store information by trapping electrons in nitrides or silicon nanocrystals,
- “resistive” memories, store information by modifying the resistance of phase-change or switching oxide materials.
Most of current activity is focused on phase-change resistive memories (PCMs). PCMs are very promising for various applications, including radiation-hard military and aerospace devices as well as faster, cheaper automotive microcontrollers.

Leti bridges the gap between fundamental research and industrial needs and brings added value at different levels of the memory R&D ecosystem:
- Leti has built a consortium of research laboratories covering the basics of PCM materials and physics.
- With its industrial partner, Leti has developed a tool for CVD deposition of PCM materials in order to address next generation high density memories.
- At the device level, Leti is proposing new materials, cell architectures and geometries for specific market requirements like embedded memories for automotive.
- At the circuit level, Leti is investigating new applications of resistive memory technologies from alternative FPGA designs to more disruptive concepts such as neuromorphic computing.
