  The past few decades have seen exponential growth in capabilities of digital
electronics primarily due to the ability to scale Integrated Circuits (ICs) to
smaller dimensions while attaining power and performance benefits. That
scalability is now being challenged due to the lack of scaled transistor
performance and also manufacturing complexities [1]-[5]. In addition, the
growing cyber threat in fabless manufacturing era poses a new front that modern
ICs need to withstand. We present a new noise based computing where the
interconnect interference between nanoscale metal lines is intentionally
engineered to exhibit programmable Boolean logic behavior. The reliance on just
coupling between metal lines and not on transistors for computing, and the
programmability are the foundations for better scalability, and security by
obscurity. Here, we show experimental evidence of a functioning Crosstalk
computing chip at 65nm technology. Our demonstration of computing constructs,
gate level configurability and utilization of foundry processes show
feasibility. These results in conjunction with our simulation results at 7nm
for various benchmarks, which show over 48%, 57%, and 10% density, power and
performance respectively, gains over equivalent CMOS in the best case, show
potentials. The benefits of Crosstalk circuits and inherent programmable
features set it apart and make it a promising prospect for future electronics.
