Dynamically re-classifying data in a shared cache

A system comprising:

• a processor including a plurality of cores, each core associated with one of a plurality of private caches;
• a first cache coupled to the plurality of private caches and having a plurality of portions, each of the portions to store entries, wherein each entry is to store state information including a classification indicator field to indicate whether the corresponding entry includes data stored according to a first location protocol, a first counter field to indicate a number of consecutive accesses to the entry by a requester core and a second counter field to indicate a number of accesses to the entry by different cores;
• a cache controller coupled to the first cache and to classify data stored in the first cache based on the state information;
• and
• a dynamic random access memory (DRAM) coupled to the first cache.
