RainierQX is a PCIe Gen4 solution with 4 PCIe lanes, supporting 4 NAND channels with each channel up to 8 CEs. A solution for the PC OEM market, it is a DRAM-less controller in 12nm FinFET design offering low power consumption and lower BOM cost for an SSD.
Dr. Zining Wu, CEO and president, stated:”The PC OEM and channel markets are facing tremendous cost pressure due to increased cost of DRAM, making RainierQX an excellent solution as a DRAM-less controller with the same peak performance as those with DRAM, benefiting from industry’s fastest 2400MT/s NAND channel interface and proprietary data path accelerators. RainierQX solution clearly outperforms other solutions in its class.”
RainierQX stands out as:
Edge technology enabling independent plane access and achieving the fastest possible read access time boosting 4K random read performance over 1 million IO/s with limited die count
Sequential read performance over 7GB/s and sequential write performance over 6GB/s
Proprietary ECC solution featuring advanced 4K LDPC technology which provides error correction capability for latest TLC and QLC, as well as power awareness multi-level decoding strategy
Large SSD capacity up to 4TB
Support of NVMe 1.4 protocol
“The SSD industry is quickly shifting from PCIe Gen3 to PCIe Gen4 technology. At the same time, single NAND die capacity is getting bigger and bigger, making high random performance harder to achieve. The RainierQX’ unique data path accelerator and independent plane operation fully take advantage of the latest NAND technology to achieve high random performance, while at the same time reducing DRAM cost. As the market builds momentum on PCIe Gen4 and beyond, InnoGrit has stayed on task, developing a well-timed roadmap of controllers, with the latest addition of RainierQX, ready to meet today’s market needs as well as addressing the next gen of SSD Platforms launching in late 2021-22,” stated Greg Wong, president, Forward Insights.
