On February 8, Samsung Electronics unveiled the world’s first 256 GB embedded Universal Flash Storage (eUFS) for use in vehicles.

eUFS memory chips for use in cars are incorporated into the advanced driver assistant systems (ADAS), infotainment systems, dashboard systems, and so on of high-end sedans, sports cars, etc. What matters most for memory chips of this type is resistance to the heat that is generated during driving. Samsung Electronics’ 256GB eUFS chip has a heat resistance range of 40 degrees Celsius below zero to 105 degrees Celsius above zero. When it comes to existing eMMC 5.0 solutions, the range is from 40 below zero to 85 above zero and from 25 below zero to 85 above zero in the storage and drive modes, respectively. 

In the 256GB eUFS chip, its temperature detection sensor sends a signal to its host application processor once the temperature of the chip reaches 105 degrees Celsius or any set temperature. Then, the temperature is lowered and the solution can contribute to the stability of the car system that includes itself.

Samsung Electronics developed temperature notification and data refresh techniques with regard to the new eUFS solution. Last month, the techniques were adopted as UFS v3.0 by the Joint Electron Device Engineering Council (JEDEC).
