Ahead-looking: Micron has outlined its reminiscence and storage roadmap for the following few years, revealing important upgrades throughout its next-generation merchandise. The plans span DDR6, LPDDR6, HBM, and NAND, because the AI infrastructure spending growth continues to push {hardware} prices greater.
Micron has detailed its 1δ (1-Delta) node because the follow-up to 1γ (1-Gamma). The brand new node, which options angstrom-level course of management and HKMG CMOS construction, will reportedly ship roughly 25% greater bit density than its predecessor when manufacturing superior DRAM merchandise.
Micron added that 1-Delta will assist next-generation reminiscence requirements comparable to DDR6 and LPDDR6, with the previous providing greater than twice the bandwidth of DDR5. The corporate, nevertheless, is positioning DDR6 as high-reliability server reminiscence for AI knowledge facilities fairly than a direct successor to DDR5 for shopper PCs.
Micron expects 1-Delta to enter quantity manufacturing in H2 2027, however there is no official launch date for DDR6 but.
Micron earlier demonstrated a 512GB DDR5 RDIMM operating at 9,200MT/s in September 2026. The corporate now says its next-generation expertise will ship 1TB RDIMMs for high-density AI workloads, and claims will probably be the business’s highest-capacity RDIMM when it enters manufacturing.
As for LPDDR6, Micron claims it would ship 35% higher energy effectivity than LPDDR5, with even larger positive aspects at some densities. Scott DeBoer, the corporate’s president and chief expertise and merchandise officer, mentioned Micron is working with a variety of companions, together with Meta, to deploy LPDDR6 reminiscence in AI knowledge facilities.
Micron additionally revealed that its future reminiscence merchandise will use 6F² (6-Characteristic-Sq.) DRAM fairly than 4F², citing price, complexity, and capacitor pitch limits that considerably scale back the latter’s scalability.
The corporate added that its next-generation DRAM merchandise will use wafer bonding and Excessive-NA EUV earlier than probably transferring on to newer supplies.
Along with 6F², Micron is reportedly growing 3D DRAM as a longer-term different, whereas introducing “vHBM,” a vertically stacked design that locations reminiscence instantly on high of the compute die. Micron claims the novel design will enhance effectivity by growing bandwidth per watt in its next-generation HBM chips.
On the storage entrance, Micron outlined manufacturing plans for its G11 NAND flash with greater than 400 layers. In comparison with G9, the brand new product targets twice the bit density, 1.5 occasions the I/O pace, and greater than 25% decrease power per knowledge switch. It should additionally reportedly enter manufacturing in H2 2027, although Micron has but to announce an official launch date.
