Introduction

Qiyuan Li is an inventor based in Wuhan, China, associated with Yangtze Memory Technologies Co., Ltd. His patent work concerns memory systems and methods for improving the decoding of stored data.

Latest Patents

The provided information identifies one patent for Li: “Memory System and Operating Method Thereof, Storage Medium.” The disclosure describes a memory device containing multiple memory cells, with a preset number of cells forming a codeword, and a controller coupled to the device. The controller obtains a first read result at one read level and, if decoding fails, obtains a second read result at a different level. It then uses information about bits flipped between the two read results to perform decoding on the second result. This approach uses read-level variation and bit-flipping information as part of the decoding process. Li is credited with 1 patent in the information provided.

Career Highlights

Li’s listed patent reflects work on memory-device operation and controller-based data decoding. The disclosed method focuses on responding to an initial decoding failure by gathering a read result at another level and incorporating the differences between results into subsequent decoding.

Collaborations

The provided information lists Lu Guo and Jie Wan as Li’s coworkers. It does not specify their roles in the patent or describe particular collaborative projects.

Conclusion

Qiyuan Li’s identified patent addresses memory-system decoding through multiple read levels and bit-flipping information, highlighting his documented contribution to memory technology.
