Ferroelectric memories have undergone a transformative evolution from conventional perovskite-based materials to modern fluorite-structured ferroelectrics, driven by the pursuit of scalable, low-power, and CMOS-compatible non-volatile memory solutions. The observation of ferroelectricity in nanoscale HfO2-based films…

Charge trap memristors (CTM) are promising candidates for nonvolatile analog units in crossbar array platforms, offering a pathway to next-generation high-density memory and synaptic arrays, due to their low-current operation and self-rectifying characteristics. However, the charge trapping process is inherently slow…

In this article, we present an efficient and concise OpenMP implementation of the Nussinov RNA folding algorithm, a well-known representative of non-serial polyadic dynamic programming (NPDP). Our goal is to develop an optimized implementation that can serve as a template for related dynamic programming applications.…

Advances in high-throughput sequencing have lowered the cost and complexity of genome sequencing, making it possible for the first time to assemble large pangenomic data sets for many species. These data sets, comprising thousands of individuals, already span from hundreds of gigabytes to petabytes, far exceeding the…

High-performance difference patterns (DPs) are critical for compact and integrated microwave array systems, particularly in monopulse tracking and beam-scanning applications. However, the design of monopulse phased arrays with steep slopes, high directivity, low sidelobes, and symmetric main lobes remains challenging…

The previous description of the cell lists algorithm lends itself to an implementation using iterators. While the iterator concept is not unique to the Rust programming language, we benefit from the Rust compiler generally optimizing iterators very well, in addition to encapsulation of mutable state and composability.…

In-memory computing based on nonvolatile synaptic arrays with computing functions has significantly improved the computing energy efficiency of neural networks. However, current synaptic devices are mostly limited to accelerating matrix-vector multiplication operators, and the differentiated requirements for device…

We present the design and characterisation of a 4.2-megapixel, wafer-scale CMOS image sensor, achieving over 5000 frames per second at full resolution. The sensor has a pixel pitch of 58 µm square pixels, thus being as large as a full 200 mm wafer. The sensor is read out on two sides and features column-parallel…

High-density memory systems require a high on-state current density (Jon) to ensure fast read speeds and large sensing margins in cross-point array applications. However, achieving high Jon in atomically thin ferroelectric tunnel junctions (FTJs) remains an unmet challenge, hindered by parasitic interfacial layer (IL)…

Background The continually increasing volume of sequence data results in a growing demand for fast implementations of core algorithms. Computation of pairwise alignments based on dynamic programming is an important part in many bioinformatics pipelines and a major contributor to overall runtime due to the associated…
