SK Hynix Developed Universal Flash Storage 2.0 64GB Solution

SK Hynix Inc. announced it has developed UFS (Universal Flash Storage) 2.0 64GB solution based on its own 16nm NAND Flash and in-house firmware and controller.

This UFS 2.0 represents a leap in performance by enabling High-Speed Gear 3 interface with dual data lanes.

UFS 2.0 is the next generation of embedded flash memory to eMMC for mobile IT gadgets which drives a remarkable boost in reading/writing speed at low power and supports high density. The company’s UFS 2.0 operates at 780MB/s and 160MB/s of sequential R/W speed and runs random R/W speed at 32,000 IO/s and 17,000 IO/s. As a result, it works three times faster in read speed than eMMC 5.1.

In addition, this UFS 2.0 utilizes ‘Command Queue’ technology used in SD solutions to handle read and write commands simultaneously to achieve data operation efficiency by preventing buffering load in multi-tasking and ordering priorities of data works. To maximize prioritized command processing feature of UFS standard, the device employs ‘Multi-Thread’ read processing internally to ensure that high priority command is serviced first irrespective of other outstanding tasks, delivering fast response to time-critical host requests for best user experience. In consequence, it realizes even better performance in speed and power consumption over eMMC.

“SK Hynix is pleased to expect the mobile devices such as smartphones to enhance their performances with the advanced UFS 2.0” said Young Joon Choi, SVP, head NAND solution development division.

UFS is forecast for installation in high end smartphones from this year and adoption in mid-low end products gradually. According to IHS Technology, the share of UFS in mobile embedded memory will take 4% in this year and grow up to 23% in 2017 and 49% in 2019.
