The AM9C1 provides about a 50% improvement in power efficiency compared to its predecessor, AM991. The 256-GB automotive SSD delivers sequential read and write speeds of up to 4,400 megabytes-per-second (MB/s) and 400 MB/s, respectively.
The AM9C1 is built on Samsung’s 5-nanometer (nm) controller and provides a single-level cell (SLC) namespace feature, delivering high performance for easier access to files with heavy data, Samsung said. Also, by switching from its original triple-level cell (TLC) state to SLC mode, read and write speeds are increased by up to 4,700 MB/s and 1,400 MB/s, respectively, while also providing the added reliability of SLC SSDs
The AM9C1 is currently sampling with key partners. Mass production is expected to start by the end of this year. To meet growing demand for high-capacity automotive SSDs, Samsung plans to offer multiple storage lineups of the AM9C1 ranging from 128 GB to 2 terabytes (TB). The industry’s largest 2-TB model is scheduled to start mass production in early 2025.
The SSD product meets AEC-Q100 Grade 2 for stable performance over a temperature range of -40°C to 105°C. For quality assurance processes, Samsung received Automotive Software Process Improvement and Capability dEtermination (ASPICE) CL3 authentication with its UFS 3.1 product in March 2024. The company also is targeting Cyber Security Management System (CSMS) certification based on ISO/SAE 21434 to enhance the reliability and stability of its automotive products.
