Qunlian Electronics is a manufacturer focusing on the research and development of memory controllers. Its PS8313 and PS8311 products are relatively famous. The PS8313 has passed the certification of Qualcomm and Huawei HiSilicon, and will soon be used in smart phones. The PS8311 supports reading 420MB/s and writing 200MB/s, and the high-end PS8313 supports the UFS2.1 storage standard, with a maximum reading of 920MB/s and writing of 550MB/s, and the transmission speed has exceeded that of the SATA 6Gb/s interface SSD

The PS8313 belongs to the second generation UFS 2.1 memory controller of Groupon Electronics. Although it has not been officially released yet, it has passed the certification of Qualcomm and Huawei HiSilicon. I believe that it is not far from its official debut. Many flagship smartphones launched this year have adopted UFS solutions.

UFS (Universal Flash Storage) is a kind of embedded storage media. It competes with the common eMMC (embedded Multi Media Card). Because of the serial full duplex data transmission mode, the transmission efficiency in all directions is higher than eMMC.

At present, most flagship mobile phones use UFS storage media, while eMMC is mostly used in the middle and low end. The competition between the two has been quite fierce, not only in the smart phone field, but also in tablet computers, smart TVs, car computers and other markets. In addition, UFS also has the form of memory card, which means it has a competitive relationship with SD Memory Card Association.
