摘要

In one embodiment, a memory management system temporarily maintains a memory page at an artificially high priority level 210. The memory management system may assign an initial priority level 212 to a memory page in a page priority list 202. The memory management system may change the memory page to a target priority level 214 in the page priority list 202 after a protection period 238 has expired.
