SK hynix's new DRAM and NAND roadmaps cover 2026 to 2028, and then 2029 to 2031, where SK hynix will have next-gen HBM4 16-Hi stacks, as well as even faster HBM4E in 8/12/16-Hi stacks between 2026-2028. SK hynix will also have custom HBM4E memory, LPDDR6 memory, and new AI-D series memory with LPDDR5X SOCAMM 2, MRDIMM Gen2, LPDDR5R, and 2nd Gen CXL LPDDR6 memory for conventional DRAM.

We'll also see PCIe Gen5 eSSD (245TB+ QLD) and cSSD, PCIe Gen6 eSSD and cSSD, as well as UFS 5.0 for standard NAND, while SK hynix also teases AI-N D (NLF and NL SSD) for between 2026 and 2028.

Into the future, SK hynix lays out its plans for 2029 to 2031 which include future-gen HBM5 and HBM5E memory standards, as well as custom HBM5 and HBM5E memory. On the conventional DRAM side of things, we'll also see GDDR7-Next, DDR6, and 3D DRAM technologies released.
