Mechanism for reducing page migration overhead in memory systems

A technique for use in a memory system includes swapping a first plurality of pages of a first memory of the memory system with a second plurality of pages of a second memory of the memory system. The first memory has a first latency and the second memory has a second latency. The first latency is less than the second latency. The technique includes updating a page table and triggering a translation lookaside buffer shootdown to associate a virtual address of each of the first plurality of pages with a corresponding physical address in the second memory and to associate a virtual address for each of the second plurality of pages with a corresponding physical address in the first memory.
