Brief

I am currently a Ph.D student and fortunately advised by Prof. Hu & Prof. Feng in Huazhong University of Science and Technology (HUST). I also obtained B.E. degree in HUST.
My research is mainly about building high-performance and fault-tolerant memory systems with emerging devices.

This blog contains some random paper reading notes and trivial thoughts.
