Samsung Electronics Co., Ltd. has begun mass production for the industry’s thinnest 12 nanometer (nm)-class, 12-gigabyte (GB) and 16GB LPDDR5X DRAM packages. As a result, this solidifies its leadership in the low-power DRAM market.

Leveraging its extensive expertise in chip packaging, Samsung delivers ultra-slim LPDDR5X DRAM packages. They create additional space within mobile devices, facilitating better airflow. Thus, it supports easier thermal control – a factor that is becoming increasingly critical, especially for high-performance applications with advanced features such as on-device AI.

“Samsung’s LPDDR5X DRAM sets a new standard for high-performance on-device AI solutions, offering not only superior LPDDR performance but also advanced thermal management in an ultra-compact package,” said YongCheol Bae, Executive Vice President of Memory Product Planning at Samsung Electronics.

“We are committed to continuous innovation through close collaboration with our customers, delivering solutions that meet the future needs of the low-power DRAM market.”

Industry’s Thinnest at 12nm

With the new LPDDR5X DRAM packages, Samsung offers the industry’s thinnest 12nm-class LPDDR DRAM in a 4-stack structure¹. Accordingly, this reduces the thickness by approximately 9% and improves heat resistance by about 21.2% compared to the previous generation product.

Additionally, it optimized printed circuit board (PCB) and epoxy molding compound (EMC)² techniques. Thus, the new LPDDR DRAM package is as thin as a fingernail at 0.65mm. This is the thinnest among existing LPDDR DRAM of 12GB or above. Also, Samsung’s optimized back-lapping³ process is used to minimize the package height.

Future Product Directions

Moreover, Samsung plans to continue expanding the low-power DRAM market. It plans to supply its 0.65mm LPDDR5X DRAM to mobile processor makers as well as mobile device manufacturers. As demand for high-performance, high-density mobile memory solutions in smaller package sizes continues to grow, the company plans to develop 6-layer 24GB and 8-layer 32GB modules into the thinnest LPDDR DRAM packages for future devices.

¹ Structure with four layers packaged together, and each layer consists of two LPDDR DRAMs.

² Material that protects semiconductor circuits from various external environments such as heat, impacts, and moisture.
