What to know about Semiconductor Innovation

Researchers from Brazil, Germany, and the U.S. have developed a theoretical framework for 'memtransistors' that could potentially exceed the Boltzmann limit of energy efficiency in semiconductor transistors. The study suggests that harnessing existing memory effects in nanoscale devices may offer a more achievable path to energy-efficient computing than previous complex methods.
