Tim Hollis on Solving Signal Integrity Challenges in Microns GDDR6X Memory

Micron recently announced GDDR6X, the new gold standard in graphics memory. To find out makes GDDR6X so remarkable, I had a chat with Tim Hollis, Micron fellow and one of the inventors of the special sauce. (Spoiler alert: we’re squeezing two bits down every wire, instead of one, giving us twice the raw bandwidth of the previous generation.) At those speeds, circuit board traces don’t behave like lines on a diagram, so keeping those bits intact takes some serious engineering. I also asked Tim about mentoring up-and-coming technical talent and serving as a Micron fellow. Learn more at
