ABSTRACT:
A system and method for managing memory data is provided. Data stored within a main memory may be requested by multiple requesters that may include one or more cache memories. When the data is provided by the main memory to a requester, it will be provided in a state that is based on the way the data was recently used by the requesters. For example, if a pattern of read-only usage has been established for the data, the data will be returned to a requester in a shared state. If data that was provided in a shared state must be updated such that the requester is required return to main memory to obtain read/write privileges, the main memory will thereafter provide the data in an exclusive state that allows write operations to be completed. This will continue until a pattern of read-only usage is again established.
