Samsung Electronics Mass-produces Automotive '256GB eUFS' with Expanded Temperature Guarantee Range
Published2018.02.08 15:38Samsung Electronics has set out to expand the premium memory market by introducing the world's first 256GB (gigabyte) eUFS (embedded Universal Flash Storage) for automobiles.
Automotive eUFS is a memory product used in next-generation Advanced Driver Assistance Systems (ADAS), infotainment, and dashboard systems of high-spec vehicles, such as luxury sedans and sports cars.
For automotive memory, heat resistance is important due to the heat generated during driving, and the newly released '256GB eUFS' has significantly extended the warranty range from -40℃ to 105℃. In the case of existing eMMC 5.0 (embedded Multi Media Card), the storage mode is guaranteed from -40°C to 85°C, and the operating mode from -25°C to 85°C.
In particular, the stability of the automotive system was enhanced by providing a solution in which, when the temperature reaches 105°C or exceeds a set temperature, the temperature sensing sensor transmits a signal to the host AP (Application Processor) to lower the temperature.
This automotive '256GB eUFS' achieves a sequential read speed of 850MB/s and a random read speed of 45,000 IOPS (Input/Output Operations Per Second) based on the existing 'JEDEC UFS 2.1' standard, and applies 'Data Refresh' technology, which moves data that has been out of service for a certain period to a new cell, thereby improving processing speed and ensuring system stability.
Samsung Electronics’ proprietary ‘Temperature Notification’ and ‘Data Refresh’ technologies, which were independently developed and patented, were adopted as the next-generation standard ‘JEDEC UFS v3.0’ by the Joint Electronic Devices Engineering Council (JEDEC) in January 2018, enabling the company to continue leading the automotive memory market.
"By guaranteeing enhanced high-temperature characteristics for automotive applications for the first time in the industry, we have provided a powerful solution that enables vehicles to deliver stable performance even in extreme conditions," said Han Kyung-hwan, Senior Vice President of the Marketing Team at Samsung Electronics' Memory Business Division. "Following our lead in the high-spec automotive memory market for luxury sedans and sports cars, we will [target] general brand automobiles "We will continue to expand our business scope to the market and lead the growth of the premium memory market," they stated.

Artificial intelligence evolving into semiconductors with smaller size and larger capacity
At Semicon Korea 2018, Kang Ho-gyu, Senior Vice President and Head of Samsung Electronics' Semiconductor Research Institute, delivered a keynote speech on semiconductor technologies and directions for the fourth industrial revolution. The semiconductor industry is expected to maintain strong momentum in 2018 due to improved global economic conditions and increased demand from IoT, autonomous vehicles, and other sectors. As examples, Dubai drone delivery will soon be commercialized, and at Amazon Go, customers no longer need to stand in line. Japan's Pepper Robot has already begun service at hotels in Japan. Changes in daily life resulting from IT advancement are occurring across multiple sectors. Among various fields, smart cities, which attracted attention as a major topic at the 2018 CES, are a prime example. Sample cities have been selected in several countries, and in Korea, Busan and Sejong have been selected as candidates, drawing attention as a future industry. This involves connecting city components through the Internet and 5G, and utilizing big data and AI to ultimately provide citizens with a safe environment.
