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.
