Cari tutti,

vi ricordiamo l'incontro SMeet di venerdì 9 Febbraio 2024 alle ore 11:30, ESCLUSIVAMENTE IN PRESENZA in aula Campisano, sede IMM-CNR.

Il meeting prevede (collegamento da remoto dello speaker):

* Speaker - Dott.ssa Valeria Bragaglia (Staff Research Scientist at IBM research Europe Zurich)

* Chair - Dott.ssa Stefania Privitera

* Titolo - A brain inspired computing approach: the role of material science

Abstract:
Deep Neural Networks have achieved excellent performance on various artificial intelligence (AI) applications, due to their ability to learn from large and unstructured sets of data. Nevertheless, the constant shuffling of big data sets between physically separated memory and processing unit in standard von Neumann architectures, leads to tremendous power inefficiencies. Dedicated neuromorphic hardware can help overcome this issue. Especially memristors are suitable for this dedicated hardware: by enabling to store and process information in the same location, they get around the biggest bottleneck for computing speed and power [1]. In this seminar I will focus on the role of materials science in the development of various devices based on Phase Change Materials and Oxide Resistive Random Access Memories, key building blocks for the realization of the artificial neural and synaptic function in neuromorphic computing. These devices rely on diverse physical mechanisms and materials and their understanding via experimental and theoretical means is pivotal to the device optimization and coupling to the higher layers of the computer architecture [2,3].
