Abstract: Various aspects provide for managing data associated with a cache memory. For example, a system can include a cache memory and a memory controller. The cache memory stores data. The memory controller maintains a history profile for the data stored in the cache memory. In an implementation, the memory controller includes a filter component, a tagging component and a data management component. The filter component determines whether the data is previously stored in the cache memory based on a filter associated with a probabilistic data structure. The tagging component tags the data as recurrent data in response to a determination by the filter component that the data is previously stored in the cache memory. The data management component retains the data in the cache memory in response to the tagging of the data as the recurrent data.
