Micron roadmap skips 4F2 for 3D DRAM as planar scaling hits atomic limits

Micron's technology day roadmap shows DRAM planar scaling reaching atomic limits, so it will skip the 4F2 cell architecture and move straight to 3D DRAM, while NAND continues scaling via stacking — all aimed at meeting AI bandwidth demands.
