I’m not the one who downvoted you, but while stacking in 3D might work for things like ram and storage, it doesn’t help the same way with cpu. They aren’t trying to get the overall die size smaller per se, but rather the node size. Generally speaking, smaller transistors = lower energy consumption + higher performance for the same number of transistors.
- patmorgan23 3y agoI wonder how practical it would be to switch to non-binary transistors. I believe some early vacuum tubes where trinary instead of binary. Probably not practical but would be interesting to see how it could fit together.
- wtallis 3y agoStorage (NAND flash) and many off-chip communication protocols (both wired and wireless) are already non-binary and use multiple discrete voltage levels. There's also a lot of interest in more or less analog storage and compute elements for ML, where it's fine to have weights and activations represented in a fundamentally fuzzy manner. But I don't think there's any promising way to perform discrete deterministic logic and computation in base 3 or higher using transistors, aside from what we already do for multi-bit quantities.
