Abstract: Embodiments are disclosed for replacing one or more pages of a memory to level wear on the memory. In one embodiment, a system includes a page fault handling function and a memory address mapping function. Upon receipt of a page fault, the page fault handling function maps an evicted virtual memory address to a stressed page and maps a stressed virtual memory address to a free page using the memory address mapping function.

Abstract: A memory controller comprises a command interface to transmit a memory command to a plurality of memory devices associated with the memory controller. The memory controller also comprises an acknowledgement interface to receive an acknowledgment status packet from the plurality of memory devices over a shared acknowledgement link coupled between the memory controller and the plurality of memory devices, the acknowledgement status packet indicating whether the command was received by the plurality of memory devices. In addition, the memory controller comprises a memory controller core to decode the acknowledgment status packet to identify a portion of the acknowledgement status packet corresponding to each of the plurality of memory devices.
