The SK Hynix ZUFS 4.0 NAND Solution Improves On-Device AI

NAND Solution ZUFS 4.0

Zoned Universal Flash Storage (ZUFS) is a NAND Flash solution designed to increase data management effectiveness. By storing data with comparable properties in the same zone of the UFS, the product a flash memory product for various electronic devices like digital cameras and mobile phones optimizes data operating system-storage device transfer.

On-Device AI: This is a technology that allows AI operations to be implemented directly on the device, bypassing the need for a physically separate server to do computation. The direct information gathering and processing capabilities of smartphones enable quick responses from AI systems and offer enhanced, personalised AI services.

According to SK Hynix, the ZUFS 4.0 is the greatest product of its kind on the market and is optimised for on-device AI from mobile devices like smartphones. The current device is expected to help the business extend its leadership in AI memory to the NAND arena, building on its success in the high-performance DRAM market, which is dominated by HBM.

Using unique technology, the ZUFS organises and stores data from smartphones in several zones based on specific attributes. The newest product, in contrast to a traditional UFS, divides and stores data in distinct zones for comparable purposes and frequencies. This increases the performance of the operating system on smartphones and improves the efficiency of storage device management.

When compared to a traditional UFS, the ZUFS reduces the amount of time needed to execute an application from a smartphone during extended hours by 45%. The product’s lifespan increased by 40% as the problem of read and write performance deterioration was resolved more than four times over.

The technology was first developed in 2019, before to the commencement of the AI boom, when SK Hynix partnered with a multinational platform service provider in anticipation of a rise in the market for high-performance NAND solutions.

Following the delivery of the ZUFS prototypes, SK Hynix and the client worked together to build the 4.0 product, which satisfies JEDEC’s requirements. In the third quarter, SK Hynix plans to start mass producing the ZUFS 4.0 with the goal of supplying different on-device AI smartphones for international businesses.

Customers are demanding better memory options as large tech businesses concentrate on developing on-device products and implementing their own generative AI applications, according to Ahn Hyun, Head of the N-S Committee at “SK Hynix will create high-performance NAND solutions to meet these expanding needs to dominate global AI memory. time and forging closer relationships with top ICT companies.”

Leading memory chip maker SK Hynix has unveiled ZUFS 4.0 (Zoned Universal Flash Storage), a major advancement for smartphone technology. The purpose of this next-generation mobile NAND technology is to enhance smartphone on-device AI features.

Recognising the Need: AI’s Storage Requirements

Advances in storage solutions are required due to the growing world of on-device AI applications in smartphones, which include capabilities like voice assistants, intelligent cameras, and facial recognition. For best results, these AI features strongly rely on effective data storage and access. AI applications are need more and more data throughput, and traditional NAND storage is finding it difficult to stay up.

ZUFS 4.0: A Focused Method for Storage

ZUFS 4.0 uses a unique architecture to carefully arrange and store smartphone data in zones that are chosen based on certain criteria, thereby addressing these issues. Data with comparable usage patterns and retrieval rates are grouped together thanks to this clever allocation. There are several advantages to this focused storage strategy:

Improved Performance

ZUFS 4.0 dramatically lowers read and write latencies by allocating commonly utilised AI data to zones that are easily accessible. This means that your smartphone’s AI apps will run more quickly and seamlessly.

Enhanced Durability

As write cycles pass, traditional NAND storage experiences a decline in performance. By intelligently controlling write operations across many zones, ZUFS 4.0 lessens this problem. This keeps the storage device operating at a steady state for a longer period of time and increases its lifespan.

Optimised Power Efficiency

The storage unit uses less power because of the optimised data organisation within zones, which simplifies data access. This means that your smartphone’s battery life will be longer.

ZUFS 4.0: A Positive Sign for On-Device AI in the Future

ZUFS 4.0, an innovation from SK Hynix, is a big step towards smartphones having strong on-device AI capabilities in the future. This technology has the ability to completely transform a number of smartphone usage characteristics, improving the efficiency and smoothness of AI-powered features. ZUFS 4.0 is expected to be included into future smartphone models from top manufacturers, ushering in a new era of intelligent mobile experiences, with mass production scheduled for Q3 2024.
