64-layer 512Gb V-NAND is stacked in 8 layers and integrated into a single package with a dedicated controller.

Samsung Electronics is mass-producing the world's first 512GB eUFS (embedded Universal Flash Storage) for next-generation mobile devices.

This '512GB eUFS' is a product made by stacking 8 layers of high-performance 64-layer 512Gb V-NAND and equipping it with a dedicated controller into a single package, doubling the capacity compared to the existing 256GB product based on 48-layer 256Gb V-NAND while maintaining the same size.

The 64-layer 512Gb 3-bit V-NAND maximizes performance and stability through the application of cutting-edge proprietary technologies, such as 'ultra-high-speed mapping technology' that can convert virtual addresses to physical addresses faster through a self-developed high-performance controller, and 'ultra-low power technology' to minimize power consumption that increases as the number of cells doubles.

In the case of the 64GB eUFS commonly used in existing smartphones, it can record 13 videos of 10 minutes each in 4K UHD (3840x2160) mode, but the 512GB eUFS can continuously record 130 videos.

It offers the largest capacity among built-in memory while delivering top-level performance. A sequential read speed of 860 MB/s, a sequential write speed of 255 MB/s, a random read speed of 42,000 IOPS (Input/Output Operations Per Second), and a random write speed of 40,000 IOPS were achieved.

With a random write speed 400 times faster than a microSD card (100 IOPS), complex tasks such as continuous shooting of high-quality photos, searching for files on a dual screen, and downloading videos can be processed quickly and more smoothly without buffering.

"The 512GB eUFS has resolved the technical issue of being unable to use high-capacity microSD cards in mobile devices due to speed degradation," said Han Jae-soo, Executive Vice President and Head of Strategy Marketing at Samsung Electronics' Memory Business Division. "Through the stable supply of the 512GB eUFS, we have contributed to global mobile companies launching next-generation products in a timely manner."
