That’s the name of the game in computers and electronics in general: faster, smaller, more dense, less power, and the one that I hardly ever hear about any more: less voltage. A silicon semiconductor voltage threshold for ‘switching states’ is approximately 0.7 volts. For Germanium devices it’s 0.3 volts. If the folks at Kepler have come up with a new material, they may have brought the switching voltage down to less than the above.................
But how do you cram more memory BETWEEN chips?
