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. This 1γ DRAM milestone builds on Micron's previous 1α (1-alpha) and 1β (1-beta) DRAM node leadership to deliver innovations that will power future computing platforms from the cloud to industrial and consumer applications to Edge AI devices like AI PCs, smartphones and automobiles. The Micron 1γ DRAM node will first be leveraged in its 16Gb DDR5 DRAM and over time will be integrated across Micron's memory portfolio to meet the industry's accelerating demand for high-performance, energy-efficient memory solutions for AI. Designed to offer speed capabilities of up to 9200MT/s, the 16Gb DDR5 product provides up to a 15% speed increase1 and over 20% power reduction compared to its predecessor.2
