Core-Shell Dual-Gate Nanowire Memory as a Synaptic Device for Neuromorphic Application

Blog Article

In this work, a synaptic device for neuromorphic system is proposed and designed to emulate the biological behaviors in the novel device structure of core-shell dual-gate (CSDG) nanowire flash memory.Floating-body effect in the device and charge trapping/de-trapping in the nitride layer are found to be effective for short-term potentiation (STP), long-term potentiation (LTP), and long-term depression (LTD), respectively.STP realizes AM FM Tuner a temporary potentiation in the artificial neural network, and it can transit to LTP through the process of rehearsal and meaningful association.The transition takes place at the 10th pulse in a permissibly optimized CSDG synaptic device.The proposed device shows a stronger capacitive coupling between the dual gates, which forms a deeper potential well for charge storing and achieves better memory performance metrics such as sensing margin and retention time.

The series of results reveal that the HOTPOINT Class 4 DU4541JCIX Electric Built-under Double Oven - Stainless Steel synaptic memory device is applicable to neuromorphic system due to the stronger gate controllability, multi-level weight adjustability, and Si processing compatibility.
