3D NAND PUF Researchers from Seoul National University developed a new hardware security technology based on commercially available 3D NAND flash memory. The approach is an adaptation of physical unclonable functions (PUFs) with the ability to hide a security key under user data when not in use and reveal it only when needed. The same memory space used for storing security keys can be repurpos... » read more

InGaOx GAA transistor Researchers from the University of Tokyo created a gate-all-around transistor made from gallium-doped indium oxide (InGaOx). Doping indium oxide with gallium suppressed oxygen vacancies, improving transistor reliability. "We wanted our crystalline oxide transistor to feature a 'gate-all-around' structure, whereby the gate, which turns the current on or off, surrounds t... » read more
