More technically, I suppose.

Is the error rate due to quantum tunneling at so many nanometers still a fundamental limit to transistor density and thus also (G)DDR and HBM performance per unit area, volume, and charge?

https://www.hackerneue.com/item?id=38056088 ; a new QC and maybe in-RAM computing architecture like HBM-PM: maybe glass on quantum dots in synthetic DNA, and then still wave function storage and transmission; scale the quantum interconnect

Is melamine too slow for >= HBM RAM?

My understanding is that while quantum tunneling defines a fundamental limit to miniaturization of silicon transistors we are still not really near that limit. The more pressing limits are around figuring out how to get the EUV light to consistently draw denser and denser patterns correctly.

>> But now, the researchers from Southampton, together with scientists from the universities of Dortmund and Regensburg in Germany, have successfully demonstrated that a beam of light can not only be confined to a spot that is 50 times smaller than its own wavelength but also “in a first of its kind” the spot can be moved by minuscule amounts at the point where the light is confined

FWIU, quantum tunneling is regarded as error to be eliminated in digital computers; but may be a sufficient quantum computing component: cause electron-electron wave function interaction and measure. But there is zero or 1 readout in adjacent RAM transistors. Lol "Rowhammer for qubits"
