RAMbo: Sideways Memory Strikes Back
What Is Z-Angle Memory and Why Is Intel Developing It?
Intel says its new stacked memory could be a game-changer, but commenters are already asking if it’s genius or just another shiny promise
TLDR: Intel is betting on a new memory design with SoftBank that could eventually beat today’s AI memory on speed, size, and power use — but it likely won’t arrive until 2029. Commenters are split between intrigued by the “sideways stacked” idea and deeply skeptical that Intel will actually turn the hype into a real product.
Intel has unveiled a big-sounding future memory project with SoftBank-backed SAIMEMORY, promising a new kind of chip design called Z-Angle Memory that could one day move more data, use less power, and cost less than today’s ultra-expensive AI memory. In plain English: Intel wants to build a better memory brick for the AI boom — just not anytime soon, because prototypes aren’t expected until 2027 and full launch may not happen until 2029. And the comments? Oh, they were not ready to hand out confetti.
The loudest reaction was basically: “Cool story, but what even is this thing?” One commenter flat-out groaned that the article explained almost nothing about how ZAM is actually different. Another swooped in with a rescue mission, linking a different explainer and saying the trick seems to be that the memory is stacked “on its side,” which instantly became the thread’s accidental comedy centerpiece. Sideways RAM? Vertical memory? The vibe was half curiosity, half “someone please draw us a picture.”
Then came the Intel trust issues. One skeptic wondered if ZAM will end up like Optane — hyped, admired, and then quietly shuffled into the graveyard of abandoned side projects. Another went even sharper, accusing Intel of its classic “throw spaghetti at the wall” investment style while partners do the hype dance. Still, not everyone was cynical: one commenter marveled that the basic memory cell has barely changed in decades, making this feel like the rare idea that could actually shake things up. So yes, the promise is huge — but the crowd is serving equal parts intrigue, eye-rolls, and popcorn.
Key Points
- •Intel said it is partnering with SoftBank subsidiary SAIMEMORY to commercialize Z-Angle Memory, a vertically stacked DRAM technology.
- •The article says ZAM could deliver 2x to 3x the capacity of HBM, along with higher bandwidth and lower energy use and cost.
- •Intel’s ZAM effort builds on technology from its Next Generation DRAM Bonding program, part of the DOE/NNSA-backed Advanced Memory Technology initiative.
- •Sandia reported a demonstration under the NGDB project that vertically bonded eight memory wafers to a base wafer using a via-in-one construct.
- •SoftBank reportedly plans to invest ¥3 billion in SAIMEMORY, with a ZAM prototype targeted for 2027 and commercialization for 2029.
