Mimicking the human brain with oxygen-engineered yttria-based memory cells

© Eszter Piros

Our work on utilizing oxygen engineering to control the resistive switching dynamics in yttria-based RRAM, recently published in Advanced Electronic Materials, has been selected to be featured on the cover of the journal. We show that via reducing the oxygen content of the yttria layer the abrupt switching characteristics are transformed to gradual, almost analog transition. Exploiting the gradual nature of the switching, the basic building blocks of neural networks, namely synapses, can be mimicked. Enhancing the complexity of these by increasing their inter-connectivity, neural networks, and finally, the human brain can be mimicked.
