Samsung is working on industry’s First 1TB memory chip for smartphones

What would you do with one-terabyte (TB) of storage on your phone? Well, Just four years after introducing the first Universal Flash Storage solution (UFS), the 128-gigabyte (GB), Samsung now says it has begun production of industry’s first one-terabyte (TB) embedded UFS, for use in next-generation mobile applications.

This means smartphone users who love more storage space like me will soon be able to enjoy storage capacity comparable to a premium notebook PC, without having to pair their phones with additional memory cards.

Cheol Choi, executive vice president of Memory Sales & Marketing at Samsung Electronics says “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,”

“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 package size (11.5mm x 13.0mm), the 1TB eUFS solution doubles the capacity of the previous 512GB version by combining 16 stacked layers of Samsung’s most advanced 512-gigabit (Gb) V-NAND flash memory and a newly developed proprietary controller.

So what does 1TB of internal storage mean to you? You will agree with me that shooting 4K videos with smartphones is becoming more common on mobile devices these days. Doing so, however, takes up so much space. With 1TB, 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 just 13 videos of the same size.

Samsung also says the memory also possesses exceptional speed, allowing users to transfer large amounts of multimedia content in significantly reduced time.

‘’At up to 1,000 megabytes per second (MB/s), the new eUFS features 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 as fast as five seconds, which is 10 times the speed of a typical microSD card. Furthermore, the random read speed has 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 and will enable smartphone users to take full advantage of the multi-camera capabilities in today and tomorrow’s flagship models.

As smartphones and software get more advanced, users also need more storage to cope. We’re however curious to know how much a 1TB smartphone will cost as Samsung has said anything about it. We should, however, expect 2019 flagship phone to come with this amount of storage.
