SK hynix Commercializes Fast Mobile DRAM LPDDR5T

SK hynix Inc. started supplying its customers with 16GB packages of Low Power Double Data Rate 5 Turbo (LPDDR5T), a mobile DRAM available that can transfer 9.6Gb/s.Since the development of its LPDDR5T in January, the company has been preparing to commercialize the product by conducting performance verification with global mobile application processor (AP) manufacturers.

The firm 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 16GB package operates in the low voltage range of 1.01 to 1.12V set by the JEDEC, and can process 77GB of data/second, which is equivalent to transferring 15 full high-definition (FHD) movies in 1s.

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 the firm’s memory packages. 

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

“Smartphones are becoming essential devices for implementing On-Device AI technology as the AI era kicks into full swing,” said Myoungsoo Park, VP and head, DRAM marketing, SK hynix. “There is a growing demand for high-performing, high-capacity mobile DRAMs in the market. We will continue to lead the premium DRAM market based on our technological leadership in AI memories, while staying in tune with market demands.“

Notes:
LPDDR: Low power DRAM for mobile devices, including smartphones and tablets, which aims to at minimize power consumption and features low voltage operation. The latest specifications are for the 7th-gen, 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-gen (5X), prior to the development of the 8th generation LPDDR6.
Mobile 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 SoC format that contains a complete set of products and systems, including computation, graphics, digital signal processing, etc., in a single chip.
On-Device AI: AI 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.
