recently,After the storage giant Micron officially released 1γ (gamma) 10nm-class DRAM memory, it has begun delivering samples of 1γ DDR5 memory to customers such as Intel and AMD, becoming the first company in the storage industry to achieve this milestone.

According to reports, among the samples of 1γ DDR5 memory delivered,Micron uses only one layer of EUV lithography, the purpose is to accelerate the mass production of advanced process memory and reduce cost investment by reducing the use of EUV.

It is worth mentioning that the node process in the DRAM memory industry has not been marked with a specific nm value, but an iterative sequence of 1a, 1b, 1c, or 1α, 1β, 1γ, where 1a is closer to 20nm, and 1γ is closer to 10nm.

1γ Memory This is the first time that Micron Memory has used EUV extreme ultraviolet lithography process.Compared with Micron, Samsung and SK Hynix rely more on EUV in the development of memory technology. Samsung has been using EUV in DRAM memory production since 2020 and plans to use more than 5 EUV lithography layers in its 6th generation 1c 10nm-class DRAM memory.

SK Hynix is ​​also introducing EUV lithography technology in 2021 and plans to adopt a similar strategy in the next generation 1c 10nm-class DRAM.

According to Micron, its previous leadership in 1α (1-alpha) and 1β (1-beta) DRAM nodes,This new milestone of 1γDRAM node will drive innovative development of future computing platforms from cloud, industrial, consumer applications to end-side AI devices (such as AIPC, smartphones and automobiles).

Micron's 1γ DRAM node will first be used in its 16GbDDR5 memory and is planned to be gradually integrated into Micron's memory product portfolio.

in,The data transfer rate of 16GbDDR5 memory can reach 9200MT/s (4600MHzx2). Compared with the previous generation products, the rate is increased by up to 15% and the power consumption is reduced by more than 20%. The capacity density output of a single wafer is increased by more than 30% compared with the previous generation.

Currently, both AMD and Intel have begun technical verification of 1γ memory.

Amit Goel, corporate vice president of AMD's Server Platform Solutions Engineering Group, said: "We are pleased to see Micron's progress on the 1γ DRAM node and have begun validation work on Micron's 1γ DDR5 memory.

We are committed to continuing to promote the development of the computing ecosystem through next-generation AMD PYC data center products and a full range of consumer processors, so close cooperation with Micron is crucial. "

Dr. Dimitrios Ziakas, vice president and general manager of Intel Memory and IO Technology, said: "The advancement of Micron's 1γ node has brought significant power consumption and capacity optimization to Intel servers and AIPCs. We are pleased to see Micron's continued innovation in DRAM technology and look forward to further improving the performance of server systems and the battery life of PCs based on these advantages."

Intel is validating Micron 1γDDR5 memory samples through its rigorous server validation process to provide our customers with high-quality, first-class server systems. "
