Samsung Electronics announced on Wednesday that it has begun mass producing hear-tolerant 10-nanometer (nm)-class 16-gigabit (Gb) LPDDR4X DRAM for automobiles.

The latest LPDDR4X features high performance and energy efficiency while significantly raising the thermal endurance level for automotive applications that often need to operate in extreme environments.

Moving a step beyond its 20nm-class ‘Automotive Grade 2’ DRAM, which can withstand temperatures from -40°C to 105°C, Samsung’s new memory chip is Automotive Grade 1-compliant, raising the high-end threshold to 125°C, the company said in a statement.

Adding to the degree of reliability under high temperatures, production at an advanced 10nm-class node is key to enabling the 16Gb LPDDR4X to deliver its leading-edge performance and power efficiency.

Even in environments with extremely high temperatures of up to 125°C, the chip’s data processing speed comes in at 4,266 megabits per second (Mbps), a 14 percent increase from the 8Gb LPDDR4 DRAM that is based on 20nm process technology, and the new memory also registers a 30 percent increase in power efficiency.

Samsung Electronics will continue to expand the portfolio of its 10nm-class DRAM products, while increasing its presence in the premium memory chip market for automobiles related to the car’s advanced driver assistance systems, central controller of self-driving cars, infortainment and gateway devices, said a company official.
