Imagine storing digital information by stacking tiny, invisible beads inside microscopic tubes. By using electric forces, these beads can be pushed in and out in a specific order to represent data. It is like a microscopic filing system that can hold massive amounts of information in a tiny space.
Digital transformation is creating a data explosion that exceeds the capacity and affordability of current storage technologies. There is an urgent need for higher storage density to keep costs manageable.
A proof-of-concept for colloidal memory including a 3D imaging microscopy protocol, nanoparticle capturing mechanisms, and the first generation of microfluidic test chips.
If you are a data center operator dealing with the skyrocketing cost of physical storage space — this project developed a colloidal memory concept that could reach 1 Tbit per square millimeter. This allows for significantly higher storage density in the same physical footprint.
If you are a hardware manufacturer dealing with the physical limits of current memory chips — this project developed a method to use nanoparticles smaller than 15 nm as data carriers. This enables the creation of ultra-compact devices with storage densities exceeding 100 Gbit per square millimeter.
If you are a chip designer dealing with the need for lower-cost high-density memory — this project developed a CMOS-controlled electrode array to manage nanoparticle stacking. This provides a path toward storage technologies that are cheaper than existing options.
Based on available project data, the long-term goal is to achieve a lower cost than existing data storage technologies, though specific price points are not provided.
No. The project is currently establishing a proof-of-concept and developing test structures and modeling tools.
Based on available project data, the project is coordinated by KU Leuven with five other university partners and one research center; licensing terms are not specified.
The system uses a CMOS circuit at the periphery of the nanoparticle array to address and control the electrodes.
The project runs from 2023-11-01 to 2026-10-31 to establish a proof-of-concept, meaning commercial deployment is likely several years beyond the project end date.
The consortium is heavily academic, consisting of 6 partners from 3 countries (BE, ES, FR). With 5 universities and 1 research center, there is a 0% industry ratio, indicating this is a fundamental research project focused on scientific validation rather than immediate commercial productization.
