Samsung Starts Producing First 512GB eUFS Storage Chips for Mobile Devices

This brings us to Samsung's announcement of the 512GB eUFS chip that should provide "unparalleled storage capacity and outstanding performance for upcoming flagship smartphones and tablets".

Samsung on Tuesday announced that it had initiated volume production of UFS NAND flash memory chips with 512 GB capacity based on its latest 64-layer 512 Gb V-NAND.

Even though Samsung is most well known for its flagship phones, it has a massive component business as well.


When will the first devices packing Samsung's 512GB eUFS storage launch? This move will double the company's current maximum of 256GB that is available on the Galaxy S8 and Galaxy Note 8.

"The 64-layer 512Gb V-NAND's advanced circuit design and new power management technology in the 512GB eUFS' controller minimize the inevitable increase in energy consumed, which is particularly noteworthy since the new 512GB eUFS solution contains twice the number of cells compared to a 256GB eUFS".

The Samsung 512GB eUFS also features strong read and write performance. To put that in a real-life scenario, a user would be able to transfer a 5GB 1080p full HD video clip in around 6 seconds. Some might find the lack of a removal storage option restrictive, but the eUFS standard has the benefit of being a lot faster, offering sequential read and write speeds of 860 MB/s and 255 MB/s, respectively. That's eight times faster than a typical microSD card. And the phones will be advanced enough to handle multiple demanding operations at once, such as downloading a video while also searching through big files in dual-app mode.


Would you still be interested in picking up the Galaxy S9 if it shipped with 500GB of internal flash storage instead of a microSD slot? An industry first, these capacious storage components are fabricated from eight 64-layer 512Gb Samsung V-NAND chips plus a controller chip in a package as pictured below. According to the company, this is expected to meet the increase in demand for embedded mobile storage, SSDs, and removable memory cards with high density and performance.

Another possible market is the imminent Microsoft/Qualcomm Windows-10-on-ARM laptops, which The Register understands will all-but-expect an LTE connection but will not be made worse by 512GB of power-sipping storage.
