My understanding is that while quantum tunneling defines a fundamental limit to miniaturization of silicon transistors we are still not really near that limit.

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 there is zero or 1 readout in adjacent RAM transistors. Lol "Rowhammer for qubits"
