Research and Analysis of Design and Optimization of Magnetic Memory Material Cache Based on STT-MRAM

摘要

This paper proposes a cache replacement algorithm based on STT-MRAM magnetic memory, which aims to make the material system based on STT-MRAM magnetic memory better used. The algorithm replaces the data blocks in the cache by considering the position of the STT-MRAM magnetic memory head and the hardware characteristics of the STT-MRAM magnetic memory. This method will be different from the traditional magnetic memory-based common cache replacement algorithm. Traditional replacement algorithms are generally designed with only the algorithm to improve the cache, and the hardware characteristics of the storage device are ignored. This method can improve the material characteristics of the STT-MRAM magnetic memory by improving the cache life and efficiency.
