Abstract
In today’s computer, there are larger sizes of the cache are using on the chip. Moreover, there is significant change has happened in the technology. Because of that change cache power efficiency has become the important issue in the processors. To solve this problem most of the researchers have proposed a different methodology to improve the cache energy efficiency. This paper review different techniques that are proposed for improving cache energy efficiency. There are different techniques discussed in this survey paper that is used to improve the cache energy at a different level of the cache. The main focus of the paper of survey is to urge the different researcher to propose different methodology so they can make the cache more efficient and energy saving.
