Samsung Starts Producing First 512-Gigabyte Universal Flash Storage for Next-Generation Mobile Devices


Setting a new threshold for mobile storage to handle ever-increasing amounts of multimedia content

Samsung Electronics announced that it has begun mass production of the industry’s first 512-gigabyte (GB) embedded Universal Flash Storage (eUFS) solution for use in next-generation mobile devices. Utilizing Samsung’s latest 64-layer 512-gigabit (Gb) V-NAND chips, the new 512 GB eUFS package provides unparalleled storage capacity and outstanding performance for upcoming flagship smartphones and tablets.

Consisting of eight 64-layer 512 Gb V-NAND chips and a controller chip, all stacked together, Samsung’s new 512 GB UFS doubles the density of Samsung’s previous 48-layer V-NAND-based 256 GB eUFS, in the same amount of space as the 256 GB package. The eUFS’ increased storage capacity will provide a much more extensive mobile experience. For example, the new high-capacity eUFS enables a flagship smartphone to store approximately 130 4K Ultra HD (3840×2160) video clips of a 10-minute duration, which is about a tenfold increase over a 64 GB eUFS which allows storing only about 13 of the same-sized video clips.

To maximize the performance and energy efficiency of the new 512 GB eUFS, Samsung has introduced a new set of proprietary technologies. The 64-layer 512 Gb V-NAND’s advanced circuit design and new power management technology in the 512 GB eUFS’ controller minimize the inevitable increase in energy consumed, which is particularly noteworthy since the new 512 GB eUFS solution contains twice the number of cells compared to a 256 GB eUFS. In addition, the 512 GB eUFS’ controller chip speeds up the mapping process for converting logical block addresses to those of physical blocks.

The Samsung 512 GB eUFS also features strong read and write performance. With its sequential read and writes reaching up to 860 megabytes per second (MB/s) and 255 MB/s respectively, the 512 GB embedded memory enables transferring a 5 GB-equivalent full HD video clip to an SSD in about six seconds, over eight times faster than a typical microSD card.

For random operations, the new eUFS can read 42,000 IOPS and write 40,000 IOPS. Based on the eUFS’ rapid random writes, which are approximately 400 times faster than the 100 IOPS speed of a conventional microSD card, mobile users can enjoy seamless multimedia experiences such as high-resolution burst shooting, as well as file searching and video downloading in dual-app viewing mode.

On a related note, Samsung intends to steadily increase an aggressive production volume for its 64-layer 512 Gb V-NAND chips, in addition to expanding its 256 Gb V-NAND production. This should meet the increase in demand for advanced embedded mobile storage, as well as for premium SSDs and removable memory cards with high density and performance.
