Abstract
We propose a technique which minimizes
inter-set write variation in NVM caches for improving its
lifetime. Our technique uses cache coloring scheme to
add a software-controlled mapping layer between groups of
physical pages (called memory regions) and cache sets. Periodically,
the number of writes to different colors of the cache
is computed and based on this result, the mapping of a few
colors is changed to channel the write traffic to least utilized
cache colors. This change helps to achieve wear-leveling.
