During the China Chip Storage Future 2023 Storage Industry Trend Summit, Yingren Technology, widely recognized as InnoGrit outside of China, announced the initiation of mass production of its enterprise-level YR S900 PCIe 5.0 SSD controller. Marking a significant breakthrough, the YR S900 stands as China's first domestic PCIe 5.0 SSD controller. Operating on an open-source RISC-V architecture, the YR S900 is engineered to align with U.S. export restrictions, ensuring a seamless design and manufacturing process of the SSD controller. While Yingren Technology remains discreet about the specific process node to produce the YR S900, it's known that the controller embodies a versatile design, with compatibility extending to mainstream NAND from eminent manufacturers, and exhibits an impressive synergy with NAND from Yangtze Memory Technologies Corp (YMTC).

The YR S900 is a quad-channel controller, offering sequential read and write speeds peaking at 14 GB/s and 12 GB/s, respectively, and is equipped with InnoGrit's third-generation ECC engine to optimize 4K LDPC encoding and decoding. This collaboration with Kioxia's XL-Flash results in a low 4K random read latency of 10us, highlighting its potential to deliver higher data throughput, increased stability, and extended service life. The YR S900 encompasses a comprehensive feature set, including FDP, SR-IOV hardware virtualization, CMB, and a range of data encryption algorithms. While the mass production of the YR S900 underscores a monumental stride in SSD solutions within China, it remains to be seen whether adopting this new Chinese technology will enter markets beyond China.
