Impact of Channel Scaling on IGZO TFT-Based 6T1C Synaptic Cells for Analog Neuromorphic Operation

Indium–gallium–zinc oxide (IGZO) thin-film transistor (TFT)-based 6T1C synaptic cells are promising for capacitor-based analog neuromorphic synapses, yet the impact of channel scaling on retention and weight-update characteristics remains insufficiently understood. In this work, calibrated technology computer-aided des...

Physically implemented analog in-memory distance computing with InGaZnO transistor-based capacitive unit

Modern edge devices increasingly require real-time adaptation to their environment without relying on cloud-based updates, which can introduce latency and security risks. To meet these demands, memory-augmented neural networks (MANNs) have gained traction for enabling adaptive on-device learning. Hardware implementatio...
