Efficient solutions to nonpolynomial (NP)-complete problems would significantly benefit both science and industry. However, such problems are intractable on digital computers based on the von Neumann architecture, thus creating the need for alternative solutions to tackle such problems. Recently, a deterministic, continuous-time dynamical system (CTDS) was proposed <xref ref-type="bibr"...
Boolean Satisfiability (SAT), the first problem proven to be NP-complete, is intractable on digital computers based on the von Neumann architecture. An efficient SAT solver can benefit many applications such as artificial intelligence, circuit design, and functional verification. Recently, a SAT solver approach based on a deterministic, continuous-time dynamical system (CTDS) was introduced [1]. This...
We consider how emerging transistor technologies, specifically ferroelectric field effect transistors (or FeFETs), can realize compact and energy efficient ternary content addressable memories (TCAMs). As Moore's Law-based performance scaling trends slow, and many computational tasks of interest are now more data-centric than compute-centric, researchers are looking to improve performance/save energy...
Tunneling field-effect transistors (TFETs) stand out among novel device technologies for low-power circuits and systems. While some TFETs exhibits behavior similar to MOSFETs, a group of emerging tunneling devices including symmetric tunneling FETs (SymFETs) and interlayer tunnel FETs (IFETs) demonstrate a bell-shaped I–V characteristic dissimilar to that of MOSFETs. They have shown the potential...
We discuss how the unique I–V characteristics offered by emerging, post-CMOS transistors can be used to enhance hardware security. Different from most existing work that exploits emerging technologies for hardware security, we (i) focus on transistor characteristics that either do not exist in, or are difficult to duplicate with MOSFETs, and (ii) aim to move beyond hardware implementations of physically...
Numerous research efforts are targeting new devices that could continue performance scaling trends associated with Moore's Law and/or accomplish computational tasks with less energy. One such device is the ferroelectric FET (FeFET), which offers the potential to be scaled beyond the end of the silicon roadmap as predicted by ITRS. Furthermore, the Ids vs. Vgs characteristics of FeFETs may allow a...
We consider how the I-V characteristics of emerging transistors (particularly those sponsored by STARnet) might be employed to enhance hardware security. An emphasis of this work is to move beyond hardware implementations of physically unclonable functions (PUFs) and random number generators (RNGs). We highlight how new devices (i) may enable more sophisticated logic obfuscation for IP protection,...
