Gate/Source overlapped heterojunction tunnel FET for non-Boolean associative processing with plasticity

This work presents a gate/source-overlapped HTFET (SO-HTFET) with Gaussian I_DS-V_GS, utilized as a single transistor distance computing cell (DCC) for associative processing (AP). With much simplified DCC, inter-cell coupling, and peripherals, SO-HTFET-based AP shows 250× lower power, much higher cell density, and performance than digital CMOS-based Boolean AP.
