Different from LRU-related caching or buffering studies, we are interested in prediction-based prefetching based on given execution traces of applications. An implementation strategy is proposed in the storage of the prefetching information with limited SRAM and run-time overheads. An efficient prediction procedure is presented based on information extracted from application executions to reduce the performance gap between NAND flash memory and NOR flash memory in reads. With the behavior of a target application extracted from a set of collected traces, we show that data access over NOR flash memory is responded effectively over SRAM that serves as a cache for NAND flash memory.
