Project description
Colloidal memory concept for achieving high-density data storage
Digital transformation has triggered a surge in data, intensifying the need for affordable data storage solutions. This demand has exerted significant pressure on storage technologies, necessitating the exploration of new concepts for low-cost, high-storage-density memories. The EU-funded FASTCOMET project employs colloidal nanoparticles as data carriers within numerous nanocapillaries to establish a proof of concept for colloidal memory. Employing two types of nanoparticles with antagonistic electrophoresis properties, the project selectively inserts them into the capillary using dielectrophoresis forces to store data. The ultimate goal is to develop an integrated device for data storage using nanoparticles smaller than 15 nm, achieving ultra-high bit densities at costs lower than traditional data storage technologies.
Objective
Data is being generated at ever-increasing rates with the widespread digital transformation in businesses and society. The continually increasing demand for affordable data storage puts tremendous pressure on storage technologies. New concepts for low-cost, high-storage-density memories are urgently needed to keep storage capabilities in line with the growing demand. FastComet is a colloidal memory concept in which colloidal nanoparticles are considered data carriers. The memory consists of a large array of nanocapillaries in which two types of nanoparticles with antagonistic electrophoresis (DEP) properties can be selectively inserted into the capillary by DEP forces. Data can be stored as the specific stacking sequence of the different particle types. A CMOS circuit at the periphery of the array addresses and controls the electrodes. The long-term aim is to develop an integrated device that is able to store data using nanoparticles smaller than 15 nm. This would ultimately result in ultra-high bit densities exceeding 100 Gbit per square millimeter and potentially reaching 1 Tbit square millimeter at a lower cost than existing data storage technologies.
In the FastComet project, we aim to establish a proof-of-concept for colloidal memory by identifying suitable nanoparticles, developing nanofabricated test structures, using advanced nanoscopy imaging techniques to demonstrate the selective manipulation of nanoparticles into passive nanocapillary arrays, and establishing a modeling framework for future technology development.
