Samsung Electronics Co., the world's largest memory chip maker, said Tuesday it has started mass production of the industry's thinnest mobile DRAM, LPDDR5X DRAM, tailored to on-device artificial intelligence.The new 12-nanometer (nm)-class 12 gigabyte (GB) and 16GB LPDDR5X DRAM packages are only 0.65 mm high, making them the thinnest LPDDR DRAM in the industry, according to Samsung Electronics.The new chip, stacking four layers of 12nm-DRAM die, is 9 percent thinner and 21.2 percent more efficient in heat resistance compared to its predecessor.Samsung Electronics said the ultra-slim LPDDR5X DRAM packages can create additional space within mobile devices, enabling high-performance applications and advanced features like 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 Bae Yong-cheol, executive vice president at Samsung Electronics.Source: Yonhap News Agency
