That's how exponential work. There is an end to it and it's not far off. Exponential transistor scaling (Moore's Law) has ended.

- kabdib 10y agoIs that really true? We're probably done in 2D, but memory devices (flash) have been scaling vertically. Of course, you have to lay them out 2D, one layer at a time. And power density is still a problem with circuitry used for computation.
- wtallis 10y agoNAND flash memory is scaling vertically at the moment, but not exponentially, and not for long. Within one or two doublings of the current layer count we'll be at the limit of what can be achieved without making further sacrifices of horizontal density, or going back to the drawing board on how 3D NAND is done. This is because 3D NAND is not manufactured like 2D NAND layers stacked one at a time. The features that run through the whole stack are hitting aspect ratios in excess of 50:1, and that can't be stretched too much further.
- petra 10y ago3D logic circuits don't suffer from an high aspect ratio , but according to data by Zvi Orbach, after 4 layers the ecnomic benefit almost stops.
