Samsung Electronics, which claims to be world leader in advanced memory technology, said it was introducing the industry's first embedded Universal Flash Storage (eUFS) for automotive applications.
Consisting of 128-gigabyte (GB) and 64GB versions, eUFS has been designed for advanced driver assistance systems (ADAS), dashboard displays and infotainment systems.
"We are taking a major step in accelerating the introduction of next-generation ADAS and automotive infotainment systems by offering the industry's first eUFS for the market much earlier than expected," said Jinman Han, Samsung's head of memory product planning and application engineering.
"Samsung is taking the lead in the growth of the memory market for sophisticated automotive applications while continuing to deliver leading-edge UFS with higher performance, density and reliability."
Embedded UFS has been used in a variety of mobile applications since early 2015 when Samsung introduced 128GB embedded memory based on the JEDEC UFS 2.0 standard, for the first time in the industry. Since then, high performance and proven quality has led to wide adoption in large numbers of mobile devices from flagship smartphones, initially, to mid market smartphones.
Configured on the latest UFS standard (JEDEC UFS 2.1), the new eUFS will provide advanced data transfer speeds and robust data reliability, the supplier said. For example, the 128GB eUFS can read data at up to 850 megabytes per second (MB/s), approximately 3.4 times faster than the 250MB/s read speed of today's eMMC 5.0 versions. It also offers about 6.4 times faster random reading than eMMC at 45,000 IOPS. This will contribute to significantly enhanced performance in future automotive infotainment systems for better managing audio content, increasing navigation responsiveness, accessing internet enabled traffic and weather reports, improving handling of hands free voice commands and speeding up rear seat social media interplay.
The new eUFS product also offers an efficient and reliable error handling process, which Samsung says is essential for next generation, in vehicle infotainment. Based on the MIPI UniPro protocol, the eUFS enables detecting and recovering from I/O error on hardware layers without having to involve the host software or restarting tasks.
Samsung's eUFS also supports advanced data refresh and temperature notification features for claimed superior system reliability. The advanced data refresh operation allows a choice of refresh methods, and provides information on the refresh unit, frequency and progress for the host device's control. This enables optimal data reliability, an essential element of automotive applications.
The Samsung eUFS equips the temperature sensor inside the controller to enable highly reliable device temperature control. This prevents it from crossing well defined upper and lower temperature boundaries, thereby allowing its NAND cells to function within a tough automotive temperature environment.
Samsung said it expects rapid adoption in the automotive market.
