Yangtze Memory announces mass production of 64-layer 3D NAND as China's tech investme

Something tells me they didn't just magically achieve 50+ years of R&D over night. :lol:


In 2020....

There's no doubt China does engage in some degree of industrial espionage, but I think that's much more an issue when it comes to military designs(Like their clone of the F35) than in this much less secretive sphere where you can buy up most of the relevant baseline info for a big engineering project via academic papers. The bulk of the tech would have been developed in academia(Particularly regarding the overall thermo-mechanical challenges and the hierarchies practical for die stacking and so on) so it'd mostly be a matter of acquiring the papers(Which can be super expensive in itself for full specs but not bound by the other commercial forces that would hinder access) to shortcut a bulk of the base R&D, from there they'd still have the sizeable engineering challenges of making a viable spec and then eventually something that was economically viable to mass manufacture from top to bottom, but you can think of that stage as hundreds of really small practical problems that are often comparatively quite easy to solve by throwing more "money"(Which usually translates to more engineers specialised in the respective problematic areas) at the issue.
