SELECTIVE FILL FOR LOGICAL CONTROL OVER HARDWARE MULTILEVEL MEMORY

Abstract:

A system includes a multilevel memory such as a two level memory (2LM), where a first level memory acts as a cache for the second level memory. A memory controller or cache controller can detect a cache miss in the first level memory for a request for data. Instead of automatically performing a swap, the controller can determine whether to perform a swap based on a swap policy assigned to a memory region associated with the address of the requested data.
