In response, this dissertation explores brain-inspired analog and in-memory computing, aiming to mimic the human brain\u0027s efficiency by merging computing and memory and thus empowering sustainable and energy-efficient AI.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EAim 1 examines the physics of adaptive oxide synaptic devices through a compact model that effectively emulates experimental findings and studies the effect of titanium doping on the resistance change mechanisms of these devices.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EAim 2 focuses on improving the performance of adaptive oxide synaptic devices. Abrupt resistance changes during operation are addressed by a thin barrier layer that controls oxygen ion movement. Furthermore, MAX phase materials are utilized in these devices for enhanced endurance, reduced off-state current, higher on-off ratio, and multi-state capability.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EAim 3 extends the application of these findings to optimize system-level performance in an analog brain-inspired chip for deep learning.
