Research Interest
I am interested in emerging memory systems and hardware security. I have been working on reducing the
performance degradation of processor security supports. I am working on finding interesting issues and solutions when
adopting data security in emerging memory architectures such as 3D-stacked DRAM and NVRAM.

Research Experiences
  • Stacked DRAM with Security Attacks
    • The purpose of this research is to reduce the performance degradation for protecting data and address against malicious security attacks.
    • Using the advantages of stacked DRAM, I expect that secure processor can have the moderate performance with data security.
    • On-going work
  • Dynamically Reconfigure Prefetcher for Diverse Memory Architectures
    • Proposed a prefetcher which can be reconfigured according to diverse memory architectures and applications.
    • For hybrid memory, prefetcher can generate prefetch requests according to each memory characteristic.
    • Published in ICCD 2016
  • Reducing the Memory Bandwidth Overheads of Multi-Core Secure Processors
    • Introduced the performance degradation of multi-core secure processors due to the increasing number of memory requests to be protected.
    • Propose efficient memory scheduling and mapping scheme for managing data and metadata in order to improve memory bandwidth utilization.
