An adaptive striping architecture for flash memory storage systems of embedded systems 论文

摘要

Flash memory is now a critical component in building embedded or portable devices because of its nonvolatile, shock-resistant, and power-economic nature. With the very different characteristics of flash memory, mechanisms proposed for many block-oriented storage media cannot be directly applied to flash memory. Distinct from the past work, we propose an adaptive striping architecture to significantly boost the system performance. The capability of the proposed mechanisms and architecture is demonstrated over realistic prototypes and workloads.
