Samsung ships industry's first 1Tbyte embedded memory

By Nick Flaherty

Samsung Electronics has started mass production of the industry’s first one terabyte embedded , created with 16 stacked layers of NAND flash.

This comes just four years after the 128Gbyte Universal Flash Storage (eUFS) chip.

“The 1TB eUFS is expected to play a critical role in bringing a more notebook-like user experience to the next generation of mobile devices,” said Cheol Choi, executive vice president of Memory Sales & Marketing at Samsung Electronics. “What’s more, Samsung is committed to assuring the most reliable supply chain and adequate production quantities to support the timely launches of upcoming flagship smartphones in accelerating growth of the global mobile market.”

Within the same 11.5mm x 13.0mm package,  the 1TB eUFS doubles the capacity of the previous 512GB version by combining 16 stacked layers of Samsung’s most advanced 512Gbit V-NAND flash memory and a newly developed proprietary controller. Smartphone users will now be able to store 260 10-minute videos in 4K UHD (3840×2160) format, whereas the 64GB eUFS widely used in many current high-end smartphones is capable of storing 13 videos of the same size.

The 1TB eUFS supports a transfer speed of 1Gbit/s, approximately twice the sequential read speed of a typical 2.5-inch SATA solid state drive (SSD). This means that 5GB-sized full HD videos can be offloaded to an NVMe SSD in five seconds, 10 times the speed of a typical microSD card. 

The random read speed has also increased by up to 38 percent over the 512GB version, clocking in at up to 58,000 IOPS. Random writes are 500 times faster than a high-performance microSD card (100 IOPS), coming in at up to 50,000 IOPS. The random speeds allow for high-speed continuous shooting at 960 frames per second.

Samsung plans to expand the production of its fifth-generation 512Gb V-NAND at its Pyeongtaek plant in Korea throughout the first half of 2019.
