Micron Begins Shipment of 1γ DRAM – Its First EUV-Based Memory Process
February 26, 2025 – SkyWater Technology has announced a strategic agreement to acquire Infineon's 200mm (8-inch) Fab 25 in Austin, Texas. This acquisition will significantly boost U.S. semiconductor manufacturing capacity, particularly in 130nm to 65nm process nodes, strengthening SkyWater’s role as a key domestic foundry.
February 25, 2025 – Micron Technology has officially launched its next-generation 1γ (1-gamma) DRAM, marking the company's first-ever use of extreme ultraviolet (EUV) lithography. The 16Gb DDR5 memory based on this cutting-edge process offers higher performance, lower power consumption, and improved manufacturing efficiency. As part of Micron’s sixth-generation 10nm-class DRAM technology, the 1γ node is expected to be a core enabler for AI, cloud computing, and next-gen computing devices.
Key Features of Micron’s 1γ DRAM
Breakthrough Performance & Efficiency
Up to 9200 MT/s data transfer rate – 15% faster than previous 1β DDR5
30% increase in bit density for higher storage capacity per chip
20% reduction in power consumption, enhancing efficiency for AI workloads and cloud servers
Enhanced Compatibility & Future Scalability
Fully JEDEC-compliant, while also supporting higher-than-standard speeds for future CPUs
CUDIMM & CXL memory modules can leverage ultra-high bandwidth capabilities
Overclocking potential exceeding 10,000 MT/s, making it ideal for high-end gaming and workstation applications
First Micron DRAM Utilizing EUV Lithography
Previously, Samsung and SK Hynix had adopted EUV for DRAM years earlier, but Micron’s 1γ process closes the gap
Combination of EUV & DUV multi-patterning helps reduce patterning complexity, improve yield, and lower production costs
High-K Metal Gate (HKMG) technology and new Back-End-of-Line (BEOL) circuits boost signal integrity and reliability
Mass Production & Market Availability
Manufacturing Locations
Micron’s Japan fab was the first to integrate EUV tools in 2024
Production is expected to scale up across Japan and Taiwan fabs
Sampling & Market Entry Timeline
Currently undergoing validation with laptop & server manufacturers
Full-scale mass production expected by mid-2025
Target applications include:
AI-powered data centers & cloud computing
AI PCs, flagship smartphones, & automotive AI
GDDR7 & LPDDR5X (up to 9600 MT/s) for next-gen GPUs & mobile devices
Why This Matters
Micron’s 1γ DRAM marks a significant technological leap for the company, aligning with the industry's rapid shift towards AI-driven computing. The introduction of EUV lithography ensures Micron remains competitive in the race against Samsung and SK Hynix, both of which have already incorporated EUV in DRAM production.
With enhanced efficiency, higher speeds, and AI-optimized design, Micron’s 1γ DRAM is poised to be a key enabler for next-generation AI computing, further cementing the company’s role in the memory industry.
