Samsung Begins Mass Production of Industry’s Thinnest LPDDR5X DRAM
Samsung’s compact LPDDR5X DRAM packages measure 0.65mm high, allowing enhanced thermal control suitable for on-device AI mobile applications. The LPDDR package stacks four layers of 12nm-class DRAM die, reducing thickness and improving heat resistance while increasing density.
Samsung Electronics, the world leader in advanced memory technology, today announced it has begun mass production for the industry’s thinnest 12 nanometer (nm)-class, 12-gigabyte (GB) and 16GB LPDDR5X DRAM packages, solidifying its leadership in the low-power DRAM market.
Leveraging its extensive expertise in chip packaging, Samsung is able to deliver ultra-slim LPDDR5X DRAM packages that can create additional space within mobile devices, facilitating better airflow. This 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.”
With the new LPDDR5X DRAM packages, Samsung offers the industry’s thinnest 12 nm-class LPDDR DRAM in a 4-stack structure,1 reducing the thickness by approximately 9% and improving heat resistance by about 21.2%, compared to the previous generation product.
By optimizing printed circuit board (PCB) and epoxy molding compound (EMC)2 techniques, the new LPDDR DRAM package is as thin as a fingernail at 0.65 millimeters (mm), the thinnest among existing LPDDR DRAM of 12GB or above. Samsung’s optimized back-lapping3 process is also used to minimize the package height.
Samsung plans to continue expanding the low-power DRAM market by supplying 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.
