The embodiment of the invention discloses a cache management method and a cache management device. Through the technical scheme, when data is about to be replaced, if access exists in a cache period (i.e., the number of accessing times is greater than 0), the data is added into a cache again; data with different numbers of accessing times are added to different positions; data with many numbers of accessing times are added to difficult-to-replaced positions; and the data accessing frequency is more considered so that more frequently accessed data are more difficult to be replaced. In addition, by aiming at the same total accessing quantity, data with long-term uniform accessing can more permanently stay in the cache than data with the short-term focused accessing, so the data more suitable for an accessing mode of the cache is remained in the cache. Further, when data stored in an adjusted page returns to the cache again, the number of accessing times is reset, so the number of accessing times in a certain time only generates once gains, and the retention of data in the cache caused by accumulated accessing quantity of the data due to mass accessing in a short time is prevented.
