Flash Memory System

1. Research goal

- Develop a buffer-aware flash management technique that eliminates unnecessary page migrations by taking into account both flash translation layer and buffer management layer

 

- Design a new flash translation layer that considers the contents of a buffer cache

 

- Design the buffer management scheme, so as to maximize the benefit of buffer-aware approach
