Keep recently accessed data in higher levels of memory hierarchy (i.e. use better memory).
Hit or miss
Hit is when data is found in that level of memory hierarchy. Miss is the complement.
Average memory access time
![{\displaystyle AMAT=t_{cache}+MR_{cache}[t_{MM}+MR_{MM}(t_{VM})]}](https://wikimedia.org/api/rest_v1/media/math/render/svg/42c7c179c9d8d238656b239b095696ce178563df)
