Neuro-synaptic RAM Researchers from the National University of Singapore (NUS) and King Abdullah University of Science and Technology (KAUST) found that a standard silicon transistor can function like a biological neuron and synapse when arranged and operated in a specific way. The team was able to replicate both neural firing and synaptic weight changes by adjusting the resistance of the b... » read more

Siemens' Bianca Ward argues that sustainability must be considered starting from the design phase to reduce the energy consumption of ICs as well as the production processes used to manufacture them. Synopsys' Adrien Tozzoli looks at how physical optics simulation can be improved by using beam synthesis propagation, a method that decomposes the optical field into a collection of beamlets to ... » read more

2D materials in 3D transistors Researchers at the University of California Santa Barbara investigated 3D gate-all-around (GAA) transistors made using 2D semiconductors. They considered three different approaches to channel stacking: nano-sheet FETs, nano-fork FETs, and nano-plate FETs. The nano-plate FET architecture, which exploits lateral stacking of 2D layers, was found to maximize the g... » read more

High-frequency signal conversion Researchers from ETH Zurich developed a plasmonic modulator capable of converting electrical signals into optical signals with a frequency of over a terahertz. The modulator is a tiny nanostructure made up of various materials, including gold, and makes use of the interaction between light and free electrons within the gold. It converts signals directly, red... » read more

Cadence's P. Saisrinivas explains the relationship between drive strength and cell delay and why it is key to choose the appropriate drive strength to meet timing constraints while minimizing power and area. Siemens' Daniel Berger and Dirk Hartmann tackle the readout problem of accurately measuring the state of a quantum system after it has undergone a quantum computation, which becomes incr... » read more

Incipient ferroelectricity Researchers from Penn State University and the University of Minnesota propose harnessing incipient ferroelectricity in multifunctional two-dimensional FETs to create neuromorphic computer memory. Materials with incipient ferroelectricity have no stable ferroelectric order at room temperature and need certain conditions to achieve an electrical charge. The FETs were ... » read more

Recording synaptic connections Researchers from Harvard University built a silicon chip capable of recording synaptic signals from a large number of neurons and used it to catalogue more than 70,000 synaptic connections from about 2,000 rat neurons. They hope the device is a step in creating a detailed synaptic connection map of the brain. The chip contains an array of 4,096 microhole elect... » read more
