Even with the numbers and diagram… seems like something to approach with doubts?
To quote one of the comments under that article:
I’m not well-versed on silicon manufacture, but that layout “stack” photo looks pretty complex and has me questioning whether that would be feasible cost effective. Not sure how this compares to a similar diagram of the stacked NAND used in SSDs. The UltraRAM stack has soooo many different elements, shapes, sizes, and locations comparatively. Not just a repeatable stack…
