Abstract
Methods and systems for memory-side shared caching include determining whether a requested memory access is directed to shared portion of memory by referencing a lock address list in a memory controller. If the requested memory access is for the shared portion of memory, it is determined whether an associated data object is present in a memory-side cache. If the associated data object is present in the memory-side cache, the memory-side cache is accessed. If the associated data object is not present in the memory-side cache, an external memory is accessed.
