| Abstract: | To improve the characteristics of no resistance to erase NAND flash memory.In this paper,the traditional loss equalization algorithm (HWL algorithm) is optimized.It mainly includes the optimization of the triggering mechanism and the combination of the existing static loss balancing strategy and the dynamic loss balancing strategy.At last,a test experiment is designed to evaluate the effect of the loss equalization algorithm.The results show that compared with the current algorithm,a good wear and balance effect is achieved,which solves the defect of being not resistant to erase NAND flash memory. |
