China's 1st Domestic PCIe 5.0 Enterprise SSD Controller Enters Mass Production

Yingren has announced that the enterprise-level YR S900 PCIe 5.0 SSD controller has entered mass production. Previously unheard of, the YR S900 represents a significant accomplishment as it’s China’s first domestic PCIe 5.0 SSD controller.

The YR S900 is a four-channel SSD controller based on the open-source RISC-V architecture. The design ensures that the YR S900 complies with U.S. export restrictions, so the company doesn’t encounter obstacles when designing and manufacturing the SSD controller. However, Yingren Technology didn’t reveal the process node to produce the YR S900.

The YR S900 embraces the speedy PCIe 5.0 interface and fully supports the NVMe 2.0 protocol. It has a somewhat flexible design, allowing for 16-channel or 18-channel configurations. More importantly, the YR S900 is compatible with mainstream NAND from all the big-name manufacturers. The PCIe 5.0 controller harmonizes especially well with NAND from Yangtze Memory Technologies Corp (YMTC).
