WebFeb 10, 2024 · They are designed to work around the problem of 'aliasing' in a direct-mapped cache, where multiple memory locations can map to a specific cache entry. This is illustrated in the Wikipedia figure. So, instead of evicting a cache entry, we can use a N-way cache to store the other 'aliased' memory locations. http://www-classes.usc.edu/engr/ee-s/457/EE457_Classnotes/EE457_Chapter7/ee457_Ch7_P1_Cache/CAM.pdf crystal williams boston university
