Analog Computing with High Precision and Reliability (Invited)

Analog devices such as memristors have been restricted to specific and low-precision application areas due to their historical limitations in precision and reliability. To solve that, we study the source of the reading noise and successfully mitigate it, achieving 2048 stable conductance levels. At the system level, we co-design a circuit architecture and programming algorithm to mitigate the device programming variations and reliability issues and demonstrate high-precision computing applications with enhanced power efficiency.
