Breaking Through the "Heat Wall" of Next-Generation Memory: University of Tokyo and Others Demonstrate New Design Pushing Antiferromagnets Toward Picosecond Operation

In chiral antiferromagnets, promising as next-generation memory materials, thinning the film thickness to 30 nanometers or less and optimizing heat dissipation has enabled ultrafast spin-reversal control that does not rely on heat. This opens a path to overcoming the speed limitations imposed by conventional thermal relaxation.

Quantum Computers Overcome Errors Through "Self-Learning": Google's New Technique That Never Stops Computation

To correct drift in control parameters that occurs during quantum computation, a Google research team has developed a method that leverages quantum error correction detection signals for reinforcement learning. By using local error rates as a metric to autonomously adjust tens of thousands of parameters, continuous calibration becomes possible without ever halting computation.

New Structure Eliminates "Electron Traffic Jams" to Zero — KAIST Nullifies Semiconductor Contact Resistance with 2D Material

A Korean research team has developed a technology that eliminates contact resistance at the junction with metal electrodes by forming continuous semimetallic and semiconducting regions within a single platinum diselenide thin film. Atomic-level observation proves the absence of electron traffic jams, contributing to lower power consumption in next-generation chips.

Toward Heat-Free "Single-Atom Memory": University of Tokyo Demonstrates New Principle for Reading and Writing Data with Zero Electric Current

A research group at the University of Tokyo has developed, for the first time in the world, a technology that reads and writes the magnetic information of a single atom using only quantum mechanical "force," without using any electric current whatsoever. Because this method can prevent heat generation from Joule heating as well as malfunctions, it represents a groundbreaking achievement toward realizing the ultimate high-density memory.

It Was EVs, Not Smartphones, That Degrade From Fast Charging: A 12-Point Gap Over 8 Years

We examine the fast-charging degradation mechanism reported by Live Science against Geotab's data from 22,700 EVs and a test of 40 smartphones. EVs show a 12-point gap over an 8-year projection, while smartphones show just 0.5 points over 500 cycles—an order-of-magnitude difference in degradation scale that this article explains.

POSTECH Achieves Stable Stacking of 10+ Layers of 14μm-Thick Chips, Measured Against HBM4's Mass-Production Benchmark of 30μm

A POSTECH research team announced that it has stably stacked more than 10 layers of 14-micrometer-thick silicon chips using low-temperature, low-pressure bonding. Compared at the same package height as 12-layer HBM, the team confirmed roughly 4x the density, but the demonstration was limited to test chips without DRAM circuitry, and integration into actual HBM or yield data have not yet been presented.
