An Analog RRAM System Quickly and Accurately Computes Matrix Equations

Computer & Electronics, Tech /

Analog computers perform calculations by manipulating physical quantities—such as electrical currents—that correspond to mathematical variables, rather than representing data with discrete binary values (0 and 1) as digital computers do. Although analog computing systems can handle general-purpose tasks effectively, they are often vulnerable to noise (i.e., background or external interference) and typically less accurate than […]

Next-Gen Memory: Tungsten-Based SOT-MRAM Provides Rapid, Low-Energy Storage

Computer & Electronics, Tech /

The ability to consistently reverse the magnetic alignment in materials, called magnetization switching, is crucial for the operation of most memory devices. One common method to achieve this involves generating a rotational force (torque) on electron spins using an electric current, a phenomenon known as spin-orbit torque (SOT). Information storage devices utilizing this effect are
