Welcome to Flash-Aware Computing
Professor, Dept. of Computer Science and Engineering, SNU
This course covers various up-to-date research topics on embedded systems.
It is intended primarily for advanced graduate students in the field of embedded systems.
Recent conference papers as well as journal papers are used in the course.
This course prepares graduate students for advanced research in flash-based storage systems/architecture areas.
The core part of the course introduces key components of flash-based storage systems (such as SSDs) in a comprehensive fashion starting from NAND flash cells to flash translation layer to systems software.
Based on the basic understanding on flash-based storage systems, students are exposed to current research topics in flash-related areas by studying recent technical papers from top systems conferences.
- Undergraduate Operating Systems or equivalent
- Undergraduate Computer Architecture or equivalent
