• Starts supplying 16 GB mobile DRAM package to global smartphone makers
• LPDDR5T to be adopted in the latest smartphones along with MediaTek Dimensity 9300 mobile processor
• “Company to continue developing high-performance DRAM products to bring ‘On-Device AI’ technology to smartphones”

Seoul, November 13, 2023

SK hynix Inc. (or “the company”, www.skhynix.com) announced today that it has started supplying its customers with 16 gigabyte (GB) packages of Low Power Double Data Rate 5 Turbo (LPDDR5T)¹, the fastest mobile DRAM available today that can transfer 9.6 gigabits per second (Gbps).

¹LPDDR: Low power DRAM for mobile devices, including smartphones and tablets, which aims to minimize power consumption and features low voltage operation. The latest specifications are for the 7th generation, succeeding the series that end with 1, 2, 3, 4, 4X, 5 and 5X. LPDDR5T is a newly developed version by SK hynix, and an upgraded product of the 7th generation (5X), prior to the development of the 8th generation LPDDR6.

Since the successful development of its LPDDR5T in January, SK hynix has been preparing to commercialize the product by conducting performance verification with global mobile application processor (AP)² manufacturers.

²Mobile AP: A semiconductor chip that serves as the ‘brain’ of mobile devices, such as smartphones or tablets. It is also the central processing unit in a system-on-chip (SoC) format that contains a complete set of products and systems, including computation, graphics, digital signal processing, etc., in a single chip.

SK hynix explained that LPDDR5T is the optimal memory to maximize the performance of smartphones, with the highest speed ever achieved. The company also emphasized that it would continue to expand the application range of this product and lead the generation shift in the mobile DRAM sector.

The LPDDR5T 16 GB package operates in the ultra-low voltage range of 1.01 to 1.12V set by the Joint Electron Device Engineering Council (JEDEC), and can process 77 GB of data per second, which is equivalent to transferring 15 full high-definition (FHD) movies in one second.

The company recently started shipping its product to a global smartphone manufacturer, Vivo, which also announced that its latest smartphones, X100 and X100 Pro, will be equipped with SK hynix’s up-to-date memory packages.

These devices will also be packed with MediaTek’s newest flagship mobile AP ‘Dimensity 9300’. In August, SK hynix confirmed that it has completed the performance verification for application with MediaTek’s next-generation mobile APs.

“Smartphones are becoming essential devices for implementing On-Device AI³ technology as the AI era kicks into full swing,” said Myoungsoo Park, Vice President and Head of DRAM Marketing at SK hynix. “There is a growing demand for high-performing, high-capacity mobile DRAMs in the market.”

³On-Device AI: Artificial intelligence technology that implements AI capabilities on the device itself, instead of going through computation in a physically separated server. AI functions can become more responsive and provide more customized AI services as smart devices are capable of collecting and computing information on its own.

“We will continue to lead the premium DRAM market based on our technological leadership in AI memories, while staying in tune with market demands,” Park added.

• LPDDR5T’s 9.6 Gbps operating speeds verified using MediaTek’s next-generation flagship mobile chipset
• SK hynix to strengthen technology leadership by supplying the world’s fastest mobile DRAM

SK hynix’s LPDDR5T (Low Power Double Data Rate 5 Turbo) has completed performance verification for application with MediaTek’s next-generation mobile APs. Developed in January 2023, the LPDDR5T is the world’s fastest mobile DRAM, achieving operating speeds of 9.6 gigabits per second (Gbps).

Defying Expectations to Achieve Groundbreaking Operating Speeds

SK hynix provided samples of its LPDDR5T to MediaTek, a leading global fabless semiconductor company, in February 2023 for testing. The performance tests were carried out using the next-generation MediaTek Dimensity flagship chipset, which is part of their Dimensity Platform series of mobile APs. Set to launch within this year, MediaTek’s next-generation flagship mobile chipset will utilize 9.6 Gbps memory—the fastest operating speed for mobile devices.

The global semiconductor industry had previously projected that operating speeds of up to 9.6 Gbps would only be achievable with future iterations such as the LPDDR6, which is scheduled to be released after 2026. SK hynix has expedited this timeline with the LPDDR5T.

Applied to a Range of Mobile Devices for 2024 Debut

As the standardization approval process with the Joint Electron Device Engineering Council (JEDEC) is already in its final stages, the LPDDR5T is gearing up for its full market debut. SK hynix predicts that the generational change of DRAM for mobile devices will accelerate from next year when products are standardized and market supply begins in earnest.

“As a result of our close collaboration with SK hynix, MediaTek’s next-generation flagship Dimensity chipset is the world’s first to be validated at LPDDR5T operating speeds up to 9.6Gbps, enabling upcoming devices to unleash an unprecedented level of mobile performance,”  said JC Hsu, Corporate Sr. Vice President and General Manager of Wireless Communications Business Unit at MediaTek. “Using this updated architecture, developers and users alike will be able to get more out of their devices than ever before.”

Sungsoo Ryu, head of DRAM Product Planning at SK hynix, said: “SK hynix’s partnership with MediaTek is set to play a key role in the LPDDR5T’s market entry. Starting with this performance verification, we will expand the scope of product supply to further strengthen the leadership of the mobile DRAM market.”
