In a recent announcement that could have a significant impact on the mobile computing space, Micron is the first 1γ (1-GAMMA)-based low power double data rate 5x (LPDDR5X) memory shipping qualification sample.

The company says the memory is designed to accelerate AI applications on smartphones with thin profiles and incredible speeds. Offering LPDDR5X speed grade (GBPS) per 10.7 Gigabit, and up to 20% power savings over previous models, Micron says the LPDDR5X can give smartphone users a faster, smoother mobile experience and longer battery life.

Micron's engineers are offering what they say is reducing the LPDDR5X package size to be the thinnest package in the industry at 0.61mm, with an 8GB and 16GB1γ-based LPDDR5X 496-Ball package. The small form factor is ideally suited for ultra-thin or foldable smartphone designs, Micron said.

“Micron's 1-gamma-based LPDDR5X memory is a game changer in the mobile industry,” said Mark Montierth, corporate VP and GM of Micron's mobile and client business unit. “This groundbreaking technology offers lightning speed and incredible power efficiency — all within the thinnest LPDDR5X package in the industry — paves the way for exciting new smartphone designs. This solution demonstrates our commitment to creating exceptional mobile experiences for the ecosystem.”

To measure performance, Micron evaluated mobile AI response times from the leading language model Llama 2 based on the 10.7 Gbps bandwidth of the 1γLPDDR5X compared to the 7.5 Gbps bandwidth of 1β (1-beta).

• When you ask for recommendations for location-based restaurants, the answer is 30% faster.
• If you translate your English audio enquiries into Spanish text for guidance, the results will be 50% or more faster.
• If you request recommendations for car buying based on vehicle type, affordability, and specific infotainment and safety features, your response could be up to 25% faster.

It is also the company's first mobile solution to leverage advanced EUV lithography, and is built on February sampling of 1γ-based DDR5 memory for next-generation CPUs in data center and client segments. Micron's optimized 1γDRAM nodes incorporate cutting-edge EUV lithography to leverage CMOS advances like the next generation high KK metal gate technology to improve transistor performance and enhance bit density.

Micron currently sampled 1γ-based LPDDR5X 16GB (GB) products to select partners, offering a wide range of capacity from 8GB to 32GB for use with 2026 flagship smartphones.
