Micron Technology, Inc. announced that it is shipping qualification samples of the world's first 1g (1-gamma) node-based low-power double data rate 5X (LPDDR5X) memory, designed to accelerate AI applications on smartphones. Delivering the industry's fastest LPDDR5X speed grade of 10.7 gigabits per second (Gbps), combined with up to a 20% power savings, 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 shrink the LPDDR5X package size to offer the industry's thinnest package of 0.61 millimeters, making it 6% thinner compared to competitive offerings, and representing a 14% height reduction from the previous generation.

The small form factor unlocks more possibilities for smartphone manufacturers to design ultraathin or foldable smartphones. The company's 1g-based LPDDR5X enables dramatic leap 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 1g LPDDR5X's 10.7 Gbps bandwidth compared to 1b (1-beta) LPDDR5X's 7.5 Gbps bandwidth, 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. This milestone builds on Micron's February sampling of 1g-based DDR5 memory for next-generation CPUs in the data center and client segments. Micron's optimized 1g DRAM node leverages CMOS7 advancements like next-generation high-K metal gate technology for improved transistor performance and incorporates 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 1g-based L PDDR5X'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 1g-based LPD DR5X 16 gigabyte (GB) products to select partners and will offer a wide range of capacities from 8GB to 32GB for use in 2026 smartphones. Additional Resources. Mobile solutions page: Mobile Memory and Storage for Phones.
