Abstract

Systems and methods for write allocation by a two-level memory controller. An example processing system comprises: a processing core; a memory controller communicatively coupled to the processing core; and a system memory communicatively coupled to the memory controller, the system memory comprising a first level memory and a second level memory; wherein the memory controller is configured, responsive to determining that a memory block referenced by a memory write request is not present in the first level memory, to allocate a new first level memory block without retrieving the memory block referenced by the request from the second level memory, wherein the memory write request is represented by an overwrite type memory write request.
