SK Hynix Inc. announced it has developed UFS (Universal Flash Storage) 2.0 64 GB (Gigabytes) solution based on its own 16 nm NAND Flash and in-house firmware and controller. This UFS 2.0 represents a groundbreaking 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 780 MB/s(Megabytes per second) and 160 MB/s of sequential read/write speed and runs random read/write speed at 32,000 IOPS and 17,000 IOPS. 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 SSD 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.
