Hokyoon Lee is the Head of System Software in Memory Forest x&D at SK hynix. He is responsible for developing the system software for CXL Memory and Pooled Memory. He Joined SK hynix in 2015 as a memory system architect, working on system-level performance analysis for emerging memory devices. From 2020, he leads the System Software team and has developed CXL Memory supported SDK called HMSDK and CXL based Pooled Memory systems. Hokyoon has a diverse background spanning software to memory devices, with expertise in the areas of compilers, computer architectures, and memory fault avoidance. He received his B.S., and Ph.D. degrees in Electronics and Electrical Engineering from Korea University in 2006 and 2015, and holds over 20 patents in the areas of memory systems and technology.
Emerging CXL Memory is driving SW ecosystem to maximize the system performance by exploiting wider bandwidth and expanded capacity. SK hynix’s HMSDK (Heterogeneous Memory Software Development Kit) enables the efficient use of the heterogeneous memory system through a bandwidth-aware allocator. In addition to these advantages, CXL Interconnect realizes the memory disaggregation and enables resource pooling & data sharing among multiple hosts. Our Multi-headed CXL Pooled Memory platform, called Niagara, supports these two key use cases as well as includes HW-assisted features for effective use of CXL disaggregated memory. SK hynix is on the leading the edge of CXL Memory innovation, ushering in a new Memory-centric era.
