Devices for Classic and Quantum Information Storage and Processing
Nowadays, micro-nanoelectronic research addresses on one side the continuous scaling of logic and memory devices, also in view of targeting low power electronics and new functionalities. These objectives have been achieved by introducing new materials, exploiting new physical mechanisms and innovative fabrication methods, and with the support of modeling, simulation and design tools. On the other side, there is an increased interest to develop new systems and new computing paradigms, which can address the current emerging societal challenges. For instance, the yearly increasing amount of generated data and the Internet of Thing applications demands for more efficient computation systems in terms of power and capability, to solve problems where the standard von-Neumann based platform fails.
In this framework, the CNR-IMM Institute has a long term and internationally recognized experience in the field of materials, technologies and simulation of logic and non-volatile memory devices. More recently, the Institute has also gained a recognized expertise in developing devices and simulations for neuromorphic and quantum computation paradigms. The institute is currently at the forefront of emerging technologies in the above fields, and the research activities are carried out in collaboration with leading Industries in the field, as well as Italian/international Universities and Research Centers.
