Micron's Memory Innovations Powering the Next Generation of AI Smartphones

Expert Insights: Enhancing AI Performance on Smartphones with Micron's Memory Innovations

The AI Hype vs. Reality in Smartphones

The smartphone industry has been buzzing with talk of AI experiences for the past few years. While manufacturers have touted on-device AI processes like video generation, the conversation often remained focused on new processors and chatbots. However, the critical role of RAM capacity and storage modules for AI performance has recently come to light, highlighted by the absence of Gemini Nano on the Google Pixel 8 and Apple's requirement of 8GB RAM for Apple Intelligence.

Micron's Role in Advancing Mobile AI

Micron, a leader in memory and storage solutions, is at the forefront of enabling better AI experiences on smartphones. Their latest offerings, the G9 NAND mobile UFS 4.1 storage and 1γ (1-gamma) LPDDR5X RAM modules, are designed to push AI capabilities beyond just increased capacity.

Key Memory Innovations for AI Phones

1. UFS 4.1 Storage:

Promise: Frugal power consumption, lower latency, and high bandwidth.
Performance: Reaches peak sequential read/write speeds of 4100 MBps, a 15% gain over UFS 4.0, with reduced latency.
Capacity: Supports up to 2TB, with a smaller physical size ideal for slim and foldable phones.

2. 1γ LPDDR5X RAM:

Performance: Delivers a peak speed of 9200 MT/s.
Efficiency: Packs 30% more transistors due to size shrinking and consumes 20% lower power.
Adoption: Micron's previous 1β (1-beta) RAM is already used in the Samsung Galaxy S25 series.

The Interplay of Storage and AI Workflows

Micron has implemented four key enhancements in their storage solutions to accelerate AI operations:

Zoned UFS: Organizes data by I/O nature for faster file location and access.
Data Defragmentation: Arranges data more efficiently, improving read speeds by up to 60% and enhancing overall user-machine interactions, including AI workflows.
Pinned WriteBooster: Isolates frequently used data in a dedicated buffer (WriteBooster) for quick access, speeding up data exchange by 30% for AI tasks.
Intelligent Latency Tracker: Monitors and optimizes performance by identifying and addressing lag events, ensuring smooth operation of both regular and AI tasks.

These features are crucial for AI models that require quick access to instruction files and weights, such as Gemini or ChatGPT, ensuring that AI tasks can be executed without impacting the performance of other essential phone functions.

Beyond RAM Capacity: Power Efficiency and Local AI

While 8GB RAM is the baseline for Apple Intelligence and 12GB is becoming standard for Android, Micron's focus extends to power efficiency. Their 1γ LPDDR5X RAM modules reduce operational voltage, contributing to better battery life. The high performance of these modules (up to 9.6 Gbps) is essential for demanding AI tasks.

Improvements in EUV lithography have also enabled a 20% jump in energy efficiency for these memory solutions.

The Road to More Private AI Experiences

Micron's advancements are not only about boosting AI performance but also enhancing day-to-day smartphone tasks. They are particularly relevant for the growing trend of local AI processing, where AI models run directly on the device without sending data to the cloud. This approach enhances privacy and speed, but requires robust system resources. Micron's memory solutions provide the necessary efficiency and speed for these on-device AI workflows, from transcribing calls to processing complex research materials.

Market Availability

Micron anticipates that major smartphone manufacturers will adopt their next-generation RAM and storage modules. Flagship models equipped with these technologies are expected to launch in late 2025 or early 2026.
