Samsung unveils 512GB mobile chip
Samsung is planning to bump up phone storage to the next level with the mass production of 512GB embedded Universal Flash Storage (eUFS) chips.
Currently, most flagship phones come with 32GB-64GB storage and the most you get is 256GB, but Samsung's new 512GB chip is double or quadruple that. Most of the Samsung flagship phones such as Galaxy Note 8 and Galaxy S8 offers 64GB of memory.
The company claims that the with latest 64-layer 5120gigabit V-NAND chips (eight of them), the new 512GB eUFS package provides record storage capacity and faster processing speeds. The new eUFS solution will enable a flagship smartphone to store approximately 130 4K Ultra HD (3840x2160) video clips of a 10-minute duration which is about a tenfold increase over a 64GB eUFS which allows storing only about 13 of the same-sized video clips, the company said.
"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. In addition, the 512GB eUFS’ controller chip speeds up the mapping process for converting logical block addresses to those of physical blocks," the company stated.
The new storage promises 860MB/s sequential reads and 255MB/s sequential writes. The company claims that the new 512GB will transfer a 5GB-equivalent full HD video clip to an SSD in 6 seconds. For random operations, the new eUFS can read 42,000 IOPS and write 40,000 IOPS, which are approximately 400 times faster than a regular microSD. As of now, the company has not revealed which devices would be getting the new 512GB memory chip.
