Which vertical-DRAM cell architecture wins (4F2 / vertical-channel-transistor / CBA-stacked), and which IDM gets to volume first (~2030)?
Does true 3D DRAM arrive before the HBM scarcity window closes, or does HBM + hybrid bonding carry the load through the decade?
Does monolithic-3D startup memory (Vertical Compute) or compute-in-memory (SEMRON) reach the socket before the IDMs ship 3D DRAM?
