Micron's 1-gamma LPDDR5X memory advances mobile AI capabilities with 10.7 Gbps speeds and 20% power savings in record-thin packages.

Micron's announcement represents a significant technical achievement in mobile memory technology. The new 1-gamma node-based LPDDR5X memory delivers 10.7 Gbps speeds with 20% power savings while being packaged in an industry-leading 0.61mm thin form factor.

The technical specifications are impressive from multiple angles. The speed improvement enables 30-50% faster AI response times in practical usage scenarios like language translation and location-based recommendations. This directly addresses a critical bottleneck in on-device AI processing – memory bandwidth – which has become increasingly important as mobile AI workloads grow more complex.

What's particularly notable is Micron's implementation of EUV lithography in this mobile memory solution. This advanced manufacturing technique, combined with next-generation high-K metal gate technology, enables the density and efficiency improvements. The industry has been gradually transitioning to EUV for leading-edge chips, and Micron's application in mobile memory demonstrates their manufacturing prowess.

The 6% thinner package compared to competitors gives Micron a meaningful advantage in the smartphone design space, where every fraction of a millimeter matters, especially for foldable devices where component stacking creates significant engineering challenges.

With qualification samples shipping now and mass production targeted for 2026 flagship smartphones, Micron is positioned to capture high-margin business in premium mobile devices. The timing aligns with industry trends toward more AI processing happening on-device rather than in the cloud, creating sustained demand for exactly this class of high-performance, energy-efficient memory.

Designed for flagship smartphones, Micron LPDDR5X memory delivers top speed grades and dramatic power savings in industry’s thinnest package

BOISE, Idaho, June 03, 2025 (GLOBE NEWSWIRE) -- Micron Technology, Inc. (Nasdaq: MU), announced today that it is shipping qualification samples of the world’s first 1γ (1-gamma) node-based low-power double data rate 5X (LPDDR5X) memory, designed to accelerate AI applications on flagship smartphones. Delivering the industry’s fastest LPDDR5X speed grade of 10.7 gigabits per second (Gbps), combined with up to a 20% power savings,¹ Micron LPDDR5X transforms smartphones with faster, smoother mobile experiences and longer battery life — even when executing data-intensive workloads such as AI-powered translation or image generation.

To meet the industry’s increasing demand for compact solutions for next-generation smartphone designs, Micron’s engineers have shrunk the LPDDR5X package size to offer the industry’s thinnest package of 0.61 millimeters,² making it 6% thinner compared to competitive offerings,³ and representing a 14% height reduction from the previous generation.⁴ The small form factor unlocks more possibilities for smartphone manufacturers to design ultrathin or foldable smartphones.

"Micron's 1-gamma node-based LPDDR5X memory is a game-changer for the mobile industry,” said Mark Montierth, corporate vice president and general manager of Micron’s Mobile and Client Business Unit. “This breakthrough technology delivers lightning-fast speeds and remarkable power efficiency — all within the industry’s thinnest LPDDR5X package — paving the way for exciting new smartphone designs. This solution demonstrates our commitment to empowering the ecosystem to create extraordinary mobile experiences."

The company’s 1γ-based LPDDR5X enables dramatic leaps in performance for mobile users by enabling faster AI insights. For example, Micron evaluated mobile AI response times from large language model Llama 2, based on 1γ LPDDR5X’s 10.7 Gbps bandwidth compared to 1β (1-beta) LPDDR5X’s 7.5 Gbps bandwidth,⁵ finding:

• Responses are 30% faster when asking for location-based restaurant recommendations.
• Results are more than 50% faster when translating a voice inquiry in English to text in Spanish to ask for directions.
• Responses can be up to 25% faster when requesting car purchase recommendations based on vehicle type, affordability and certain infotainment and safety features.⁶
  

Now ramping in Micron’s mobile portfolio, Micron’s 1γ-based LPDDR5X is the company’s first mobile solution to leverage advanced EUV lithography — providing customers with early access to the latest performance and power efficiency advancements, based on the industry’s most advanced memory node technology. This milestone builds on Micron’s February sampling of 1γ-based DDR5 memory for next-generation CPUs in the data center and client segments. Micron's optimized 1γ DRAM node leverages CMOS⁷ advancements like next-generation high-K metal gate technology for improved transistor performance and incorporates leading-edge EUV lithography for enhanced bit density.

As energy-intensive mobile AI workloads are increasingly processed on-device rather than only in the cloud, low-power chips are crucial for devices like smartphones, tablets and laptops, which need to conserve power while performing AI computations.

Micron’s 1γ-based LPDDR5X’s significant 20% power savings will allow mobile users to enjoy their favorite AI applications, games and video content longer on a single charge. In addition, as AI intensifies the need for powerful, energy-efficient compute, data center servers, intelligent vehicles and AI PCs may also increasingly adopt LPDDR5X for its unique blend of optimized power efficiency and high performance.

Micron is currently sampling 1γ-based LPDDR5X 16 gigabyte (GB) products to select partners and will offer a wide range of capacities from 8GB to 32GB for use in 2026 flagship smartphones.
