KAIST team catches HZO memory films forming new domains while older ones spread

KAIST researchers imaged hafnium zirconium oxide memory films switching by two processes at once, with new polarized domains forming while existing ones grew. A model tying that picture to device electrical data offers a basis for tuning write speed and uniformity, though the account reports no switching times.

Tokyo spiking-network model predicts an event's identity, timing and odds from one neuron population

University of Tokyo researchers taught a 1,000-neuron spiking network to forecast an event's identity, timing and probability using only local learning rules. It shows one circuit can be enough in simulation, on a task with two possible events.

On-chip gradient descent trains photonic circuits to 0.26% matrix error

INSPIRE, a method that trains photonic chips on the hardware itself, produced matrices with 0.26% relative error, its developers report. The gradients are measured on the fabricated device, so training does not depend on a software model of the chip.

Texas A&M simulations find ions ease electron hopping in a zinc framework material

Texas A&M simulations show that ions inside a zinc-based metal-organic framework make it easier for electrons to move through the material. The coupling matters for adaptive, neuron-like analog hardware, but the study maps a mechanism in one material and builds no device.

Spin waves imaged inside a nano-oscillator launch harder from one edge than the other

A Gothenburg and HZB team filmed magnetization dynamics inside a CoFeB spin Hall nano-oscillator at BESSY II. Simulations matched the movies only after grain boundaries, weakened anisotropy and the Dzyaloshinskii-Moriya interaction were added.

Retina-inspired sensors are the part of neuromorphic computing that has already shipped

The 20-watt brain frames the ambition of brain-inspired hardware. The working examples are event cameras tracking debris in orbit and a low-power processor sold by Australia's BrainChip, running alongside GPUs.

A Nature Perspective puts sixteen years of self-assembling memristor work under one name

The Perspective calls them self-organizing memristive networks and applies mean-field theory, graph theory and disordered-systems physics to their conductance dynamics, with the energy saving still stated as a motivation.

MIT gives a nanoscale switch a memory by cushioning its electrodes with soft polymer

A thin viscoelastic layer of PDMS keeps two metal electrodes from snapping together and holds the history of voltages applied to them. Integrating a sensor with that memory is the team's next project.

Collective skyrmion switching produced an artificial synapse that works at room temperature

An international team including the University of Edinburgh set synaptic weights in Fe3GaTe2 by turning a whole skyrmion lattice into stripes, with no cooling. The 0.66 picojoule energy figure is a projection.

TU Graz pulled oxygen out of a battery anode on purpose, and lithium moved faster

A 300 C bake in low oxygen turned pristine lithium titanate from a poor ion conductor into a better one without touching the formula. The published account carries no number for how much better.

ORNL says the lipid bilayer itself remembers, putting membranes on the neuromorphic parts list

Oak Ridge researchers report memristance and memcapacitance in the same model membrane, which turns lipid chemistry into a hardware design variable rather than biological background.
