Samsung Electronics has developed the industry’s first PCIe 4.0 automotive solid state disk (SSD) based on eighth-generation vertical NAND (V-NAND) with a 2Tbyte version shipping in early 2025.
The initial 256GB AM9C1 automotive SSD from Samsung has 50% higher power efficiency than previous Samsung SSDs, with sequential read and write speeds of up to 4,400 megabytes-per-second (MB/s) and 400MB/s, respectively.
The SSD uses a 5nm V-NAND triple level cell (TLC) flash for data storage but also has a single-level cell (SLC) feature called Namespace. Switching from TLC to SLC mode boosts read and write speeds of up to 4,700MB/s and 1,400MB/s, respectively, while also benefiting from the added reliability of SLC but with a third the storage density.
A 2Tbyte version is scheduled to start mass production early next year.
High density SSDs are increasingly important for software defined vehicles and for storing more image data.
Through intensified board-level tests, Samsung’s new auto SSD satisfies the automotive semiconductor quality standard AEC-Q100 Grade 2, ensuring stable performance over a wide temperature range of -40°C to 105°C.
To further meet the high standards of the automotive industry in terms of durability and stability, which is especially key for NAND-based multi-level devices, Samsung also conducts various quality assurance processes. The company received ASPICE CL3 authentication4 for its UFS 3.1 product in March this year.
To obtain CSMS certification based on ISO/SAE 21434,5 Samsung will continue to actively enhance the technological reliability and stability of its automotive solutions.
“ASPICE and ISO/SAE 21434 certifications are milestones that affirm the reliability and stability of our technology,” said Hwaseok Oh, Executive Vice President at Samsung Electronics’ Memory Business. “Beyond these achievements, Samsung will continue to elevate its product stability and quality by consistently providing the best solution to key partners.”
“We are collaborating with global autonomous vehicle makers and providing high-performance, high-capacity automotive products,” said Hyunduk Cho, Vice President and Head of Automotive Group at Samsung Electronics’ Memory Business. “Samsung will continue to lead the Physical AI1 memory market that encompasses applications from autonomous driving to robotics technologies.”
The 256GB AM9C1 is currently being sampled by key partners and is expected to begin mass production by the end of this year.
Samsung plans to offer multiple storage capacities for the AM9C1 ranging from 128GB to 2 terabytes (TB) to address the growing demand for high-capacity automotive SSDs.
