This is the second product after the 128GB eUFS for automobiles last September.
Samsung Electronics plans to pre-empt the next-generation car memory market by supplying the products to global car makers and electronic equipment makers. Automotive eUFS is one of the essential components for autonomous driving, as a memory product for the next-generation advanced driving assist system (ADAS), infotainment and dashboard system of premium cars such as luxury sedans and sports cars.
Meanwhile, according to market researcher IHS Markit, the market is expected to double to USD 1,22 million this year from $ 692 million in 2014. It is expected to continue to grow at a CAGR of 11.4% until 2023.
Samsung Electronics has improved reliability and speed considering the characteristics of automotive semiconductors, which have a much longer life span than smartphones and must withstand heat, vibration and shock. The 256GB eUFS, which went into mass production, greatly expanded the operating temperature environment from -40 ° C to 105 ° C. In the case of the existing eMMC 5.0, the storage mode can withstand temperatures from -40 ° C to 85 ° C, and the drive mode from -25 ° C to 85 ° C.
It also provides a solution that allows the temperature sensor to send a signal to the host AP (application processor) to lower the temperature when it gets hotter than 105 degrees or a set temperature. Samsung Electronics said it has improved processing speed and system safety by applying a "data refresh" technology that moves data past a certain period of time to a new cell. The two technologies were adopted last month by the International Organization for Standardization (JEDEC) in the semiconductor sector as the next-generation standard called JEDEC UFS v3.0.
On the other hand, the industry expects that Samsung Electronics will remain unrivaled in the field for the time being because Samsung Electronics is the only company to produce eUFS for automobiles among NAND flash makers and Harmando affiliate, an automotive electronics component maker.
SK Hynix is currently preparing to release eUFS products from 64GB to 256GB, but it is said that there are no products in production. Other competitors, such as Toshiba, have not released eUFS for automobiles yet.
Han Kyung-hwan, managing director of marketing department of Samsung Electronics Memory Division, stated, "We will expand our business scope to the general brand automobile market following the luxury automobile memory market such as luxury sedan and sports car in the future."
