128GB embedded universal Flash targets next-gen ADAS
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.
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.
Configured on the most up-to-date UFS standard (JEDEC UFS 2.1), the new Samsung 128GB eUFS can read data at up to 850MB/s, which is approximately 3.4 times faster than the 250MB/s read speed of today’s eMMC 5.0 solutions. It also offers about 6.4 times faster random reading than eMMC at 45,000 IOPS.
The new eUFS solution also features an efficient and reliable error-handling process, which 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.
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.
For thermal management, the Samsung eUFS comes with a temperature sensor inside its controller to enable highly reliable device temperature control. This prevents the eUFS from crossing well-defined upper and lower temperature boundaries, allowing its NAND cells to flawlessly function within a tough automotive temperature environment.
