June 6, 2025, Boise, Idaho — Micron Technology, Inc. (Nasdaq: MU) today announced that it has begun shipping the world's first LPDDR5X memory certified samples based on the 1γ (1-gamma) process node. This product is specifically designed to accelerate AI applications on flagship smartphones. Micron's LPDDR5X memory offers industry-leading speeds of up to 10.7 Gb/s (Gbps) while reducing power consumption by up to 20%, delivering faster, smoother mobile experiences and longer battery life for smartphones, even when performing data-intensive tasks such as AI translation or image generation.

To meet the growing industry demand for compact solutions in next-generation smartphones, Micron engineers have successfully reduced the LPDDR5X package size to an industry-leading 0.61 millimeters², which is 6% thinner than competitors³ and 14% shorter than the previous generation⁴. The smaller form factor opens up new possibilities for smartphone manufacturers to achieve ultra-thin or foldable designs.

Mark Montierth, Micron's corporate vice president and general manager of the Mobile and Client Business Unit, stated, “Micron's LPDDR5X memory based on the 1γ (1-gamma) node will bring significant transformation to the mobile industry. This breakthrough technology achieves exceptional speed and energy efficiency with the industry's thinnest LPDDR5X packaging, opening new opportunities for innovative designs in next-generation smartphones. This solution underscores Micron's commitment to empowering the ecosystem and delivering exceptional mobile experiences."

Micron's LPDDR5X based on the 1γ (1-gamma) node delivers a significant performance boost for mobile devices, accelerating AI insights and providing an enhanced user experience. For example, in mobile AI response time tests based on the large language model Llama 2, compared to LPDDR5X based on the 1β (1-beta) node with a bandwidth of 7.5 Gbps, LPDDR5X based on the 1γ node with a bandwidth of 10.7 Gbps delivers the following improvements: 5

When asking for location-based restaurant recommendations, response speed improves by 30%

When using navigation features, the response speed for translating English voice queries into Spanish text improves by over 50%

When asking for car purchase recommendations based on vehicle type, budget range, and specific infotainment and safety features, response speed can improve by up to 25%

Micron's 1γ-based LPDDR5X is the company's first mobile solution to adopt advanced EUV lithography technology and is currently being gradually adopted across Micron's mobile product portfolio. This product leverages industry-leading memory node technology, enabling customers to experience breakthroughs in performance and energy efficiency. This significant advancement builds on Micron's February release of 1γ DDR5 memory samples for next-generation CPUs targeting data center and client segments. Micron's optimized 1γ DRAM node incorporates CMOS technology, such as next-generation HKMG (High-K Metal Gate) technology to enhance transistor performance, and leading-edge EUV lithography to increase capacity density.

Energy-intensive mobile AI workloads are increasingly being processed on edge devices rather than relying solely on the cloud. Low-power chips are critical for devices like smartphones, tablets, and laptops that require excellent energy efficiency when performing AI computations.

Micron's 1γ-based LPDDR5X can significantly reduce power consumption by 20%, enabling mobile device users to enjoy AI applications, games, and video content for longer on a single charge. Additionally, as AI applications demand higher performance and lower power consumption, devices such as data center servers, smart cars, and AI PCs may increasingly adopt LPDDR5X memory to leverage its exceptional combination of high performance and energy efficiency.

Currently, Micron has begun sampling its 16GB LPDDR5X products based on the 1γ node to select partners and will offer multiple capacities ranging from 8GB to 32GB for flagship smartphones in 2026.

1. Compared to Micron's previous-generation LPDDR5X.
2. Package thickness varies by capacity; Micron's 8GB and 16GB LPDDR5X based on the 1γ process have a 496-ball package thickness of 0.61 millimeters.
3. According to Micron's competitive market research and intelligence data, competing products have a package thickness of 0.65 millimeters.
4. The package thickness of Micron's 16GB LPDDR5X based on the 1β process is 0.71 millimeters.
5. The following examples are based on data calculations for LPDDR5X devices operating at 9.6 Gbps and 7.5 Gbps data rates.
6. The test requires the Llama 2 model to recommend 10 SUV models under priority constraints: user demand weighting is budget, Apple CarPlay compatibility, and emergency braking, blind spot monitoring
7. Parking sensors and all-wheel drive system. The recommended vehicle prices are all within the budget range of $23,000 to $37,000.
8. Complementary Metal-Oxide-Semiconductor
