Samsung produces new storage system for driverless cars

Samsung announced that it is introducing the industry’s first embedded Universal Flash Storage (eUFS) solution for use in next-generation automotive applications.

Consisting of 128-gigabyte (GB) and 64GB versions, the new eUFS solution has been designed for advanced driver-assistance systems (ADAS), next-generation dashboards and infotainment systems that provide comprehensive connected features for drivers and passengers worldwide.

Jinman Han, Samsung SVP of memory product planning says, “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 solution for the market much earlier than expected.

“Samsung is taking the lead in the growth of the memory market for sophisticated automotive applications while continuing to deliver leading-edge UFS solutions with higher performance, density and reliability.”

Embedded UFS solutions have 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, the high performance and proven quality of UFS have led to its wide adoption in large numbers of mobile devices from flagship smartphones initially, to also now in mid-market smartphones.

Configured on the most up-to-date UFS standard (JEDEC UFS 2.1), the new Samsung eUFS will provide advanced data transfer speeds and robust data reliability.

For example, the new Samsung 128GB eUFS can read data at up to 850 megabytes per second (MB/s), which is approximately 3.4 times faster than the 250MB/s read speed of today’s eMMC 5.0 solutions.

The new eUFS solution also features an efficient and reliable error-handling process, which is essential for next-generation in-vehicle infotainment.

In addition, the Samsung eUFS supports advanced data refresh and temperature notification features for 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.
When it comes to thermal management, the Samsung eUFS equips the temperature sensor inside the controller to enable highly reliable device temperature control.

This prevents the eUFS from crossing well-defined upper and lower temperature boundaries, thereby allowing its NAND cells to flawlessly function within a tough automotive temperature environment.
