This is interesting. Researchers are trying to improve Flash memory density and retention time by using graphene structures. From IEEE Spectrum:
Nanotechnology has a somewhat infamous relationship with flash memory. It has usually taken on the role as its adversary, such as in the case of Nantero or IBM’s Millipede project, and walked away with less than encouraging results.
Researchers from UCLA, IBM’s T.J. Watson Research Center, Samsung Electronics, Aerospace Corporation, and the University of Queensland, team led by Kang Wang have recently published in ACS Nano an article entitled “Graphene Flash Memory” that demonstrates that graphene may have what it takes to outperform current flash memory technology.
As I have suggested in my post from last week, researchers are not breaking their backs trying to overcome graphene’s lack of band gap as much now as they are instead looking for ways to exploit its intrinsic strengths.
In this case, the researchers were trying to take advantage of graphene’s high density of states, high work function, and atomic thinness.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
