Endurance Awarded Compiling Optimization

The unbanlanced updating frequency of data reduces the endurance of the whole non-volatile main memory that affects the system’s stability significantly. Wear-leveling techniques are effective methods to increase the endurance of non-volatile memory. In this paper, we propose a pure software based l...

Summary:The unbanlanced updating frequency of data reduces the endurance of the whole non-volatile main memory that affects the system’s stability significantly. Wear-leveling techniques are effective methods to increase the endurance of non-volatile memory. In this paper, we propose a pure software based low cost wear-leveling method, called writing balance aware mandatory rewriting insertion optimization（WBAMRI）, to improve the dynamic wear-leveling techniques.This method uses the mandatory rewriting operation combined with simple dynamic wear-leveling techniques to switch the code area to hot area dynamically. From the result of simulation, we can see that： 1） Compared with dynamic wear-leveling techniques, our ware-leveling method makes the endurance of non-volatile memory 6 times longer; 2） Compared with static wear-leveling techniques, our method nearly gets the same endurance but without the complex hardware design and the lose of memory access performance.
