Abstract
A system and method for managing a memory system. A system includes a plurality of processing entities and a cache which is shared by the processing entities. Responsive to a replacement event, circuitry may identify data entries of the shared cache which are candidates for replacement. Data entries which have been identified as candidates for replacement may be removed as candidates for replacement in response to detecting the data entry corresponds to data which is shared by at least two of the plurality of processing entities. The circuitry may maintain an indication as to which of the processing entities caused an initial allocation of data into the shared cache. When the circuitry detects that a particular data item is accessed by a processing entity other than a processing entity which caused an allocation of the given data item, the data item may be deemed classified as shared data.
