Abstract
An apparatus is described. The apparatus includes a memory controller to interface with a multi-level memory, where, an upper level of the multi-level memory is to act as a cache for a lower level of the multi-level memory. The memory controller has circuitry to determine: i) an original address of a slot in the upper level of memory from an address of a memory request in a direct mapped fashion; ii) a miss in the cache for the request because the slot is pinned with data from another address that competes with the address; iii) a partner slot of the slot in the cache in response to the miss; iv) whether there is a hit or miss in the partner slot in the cache for the request.
