SOT-MRAM To Challenge SRAM
By Bryon Moyer - 13 Jan, 2022 - Comments: 1

In an era of new non-volatile memory (NVM) technologies, yet another variation is poised to join the competition — a new version of MRAM called spin-orbit torque, or SOT-MRAM. What makes this one particularly interesting is the possibility that someday it could supplant SRAM arrays in systems-on-chip (SoCs) and other integrated circuits. The key advantages of SOT-MRAM technology are the pr... » read more

Security ICs with multi-beam Leti, a research institute of CEA Tech, and Mapper Lithography have developed a new application for its multi-beam, direct-write lithography technology—security. In 2016, Mapper Lithography introduced the FLX-1200, a direct-write, multi-beam e-beam system. Using a 5-kV acceleration voltage, a beam generator creates an electron beam about 3cm in diameter. Then,... » read more

Space elevators Last year, Pennsylvania State University disclosed a technology called benzene-derived carbon nanothreads or sometimes called diamond nanothreads (DNTs). DNTs resemble carbon nanotubes. They are tiny hollow cylindrical tubes that are stronger than steel, but they are also brittle. Basically, DNTs are 1D structures with poly-benzene sections, which are connected by Stone–Wa... » read more

Ink FETs The University of Pennsylvania has developed a new way to make chips by using nanocrystal inks. The devices, dubbed nanocrystal field-effect transistors (FETs), could be used one day to develop chips for flexible and wearable applications In the lab, researchers devised spherical nanoscale particles. These particles, which have electrical characteristics, were dispersed in a liquid... » read more
