Researchers from Japan's Tohoku University have developed a nonvolatile microcontroller unit (MCU) which achieves both high performance and ultra-low power by utilizing spintronics-based VLSI design technology and STT-MRAM memory.

The researchers used several new techniques to create an efficient and fast device. Each module's power supply is controlled independently, which eliminates wasteful power consumption, while a memory controller and a reconfigurable accelerator module are used to relax data transfer bottlenecks. These new techniques enabled the researchers to achieve ultra-lower power consumptioN (47.14 uW) at 200Mhz.
