The addition of internet connections to many billions of ‘terminal devices’ (e.g. sensors, controllers, data loggers, etc.) especially wireless, has amplified the demand for non-volatile memory that offers low power, low cost, high speed, and high write endurance. IOT terminal devices often must operate for years, powered by small batteries or small amounts of harvested energy. SOT memory consumes 1000’s of times less energy and delay than Flash, the industry’s leading non-volatile memory. SOT also offers key advantages over other emerging memories that are also positioned for this application, such as RRAM and STT.
