>Micron Announces Shipment of 1γ (1-gamma) DRAM: Pioneering Memory Technology Advancements for Future Compute Needs
>BOISE, Idaho, Feb. 25, 2025 (GLOBE NEWSWIRE) -- Micron Technology, Inc. (Nasdaq: MU), today announced it is the first in the industry to ship samples of its 1γ (1-gamma), sixth-generation (10nm-class) DRAM node-based DDR5 memory designed for next-generation CPUs to ecosystem partners and select customers.
>Improved bit-density output — Micron’s 1γ node, leveraging EUV lithography, design optimizations and process innovations, results in greater than 30% more bits-per-wafer output over the previous generation3 and the ability to scale memory supply efficiently.

DRAM stores data in highly dense capacitors, the transistors in these capacitors are different from the logic transistors in CPUs & GPUs.
It's very difficult to apply the high aspect ratio trench etching needed to make those DRAM capacitors at lower geometries.
