An Efficient B-Tree Layer for Flash-Memory Storage Systems

摘要: With a significant growth of the markets for consumer electronics and various embedded systems, flash memory is now an economic solution storage systems design. For index structures which require intensively fine-grained updates/modifications, block-oriented access over could introduce number redundant writes. It might not only severely degrade overall performance but also damage reliability memory. In this paper, we propose very different approach efficiently handle updates/modifications caused by B-Tree The implementation done directly translation layer (FTL) such that no modifications to existing application are needed. We demonstrate proposed methodology significantly improve system and, at same time, reduce overheads flash-memory management energy dissipation, when adopted
