Power/Performance Bits: Jan. 7


Ferroelectric FET Researchers at Purdue University developed a ferroelectric transistor capable of both processing and storing information. The ferroelectric semiconductor field-effect transistor is made of alpha indium selenide, which overcomes the problem of ferroelectric materials not interfacing well with silicon. “We used a semiconductor that has ferroelectric properties. This way tw... » read more

Encryption chip A team at MIT developed a new chip to lower the power consumption of public-key cryptography for IoT devices. Software execution of encryption protocols require more energy and memory space than embedded IoT sensors can typically spare, given the need to maximize battery life. The new chip is hardwired to perform public-key encryption and consumes only 1/400 as much power as... » read more
