Samsung Embedded Universal Flash Storage Solution for Automotive

64GB and 128GB

Samsung Electronics Co., Ltd. is introducing an embedded Universal Flash Storage (eUFS) solution for use in next-generation automotive applications.

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

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,” said Jinman Han, SVP, memory product, planning and application engineering, Samsung. “Samsung is taking the lead in the growth of the memory market for sophisticated automotive applications, while continuing to deliver UFS solutions with higher performance, density and reliability.

Embedded UFS solutions have been used in a variety of mobile applications since early 2015, when the company introduced 128GB embedded memory based on the JEDEC UFS 2.0 standard for the first time. Since then, the performance and quality of UFS has led to its adoption in numbers of mobile devices from flagship smartphones initially, to also now in mid-market smartphones.

Configured on the up-to-date UFS standard (JEDEC UFS 2.1), the firm’s eUFS will provide advanced data transfer speeds and robust data reliability. For example, the company’s 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 IO/s. This will contribute to enhanced performance in upcoming automotive infotainment systems for 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.

This 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, it enables detecting and recovering from I/O error on hardware layers, without having to involve the host software or restarting tasks.

In addition, the eUFS supports data refresh and temperature notification features for system reliability. The 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 data reliability, an essential element of automotive applications.

When it comes to thermal management, this eUFS equips the temperature sensor inside the controller to enable 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.

In light of the eUFS’ performance and reliability, the company expects rapid adoption in the automotive market. The firm will continue to satisfy the storage needs of automotive manufacturers by offering a variety of advanced eUFS lineups, while more thoroughly addressing the increasing demand for memory solutions in other market segments.

(*) MIPI UniPro is a general purpose, unified protocol that services a range of interface needs in mobile and connected devices. The interface was developed by the MIPI Alliance UniPro Working Group and has been available since 2007. Its current version v1.61 was released in 2015.
