Storing Data in Persistent Hybrid Memory |
摘要 |
Storing data in persistent hybrid memory includes promoting a memory block from non-volatile memory to a cache based on a usage of said memory block according to a promotion policy, tracking modifications to the memory block while in the cache, and writing the memory block back into the non-volatile memory after the memory block is modified in the cache based on a writing policy that keeps a number of the memory blocks that are modified at or below a number threshold while maintaining the memory block in the cache. |

1. A method for storing data in persistent hybrid memory, comprising:
identifying a memory block in non-volatile memory to promote to a cache according to a promotion policy that indicates the usage of the memory block; promoting the memory block from non-volatile memory to the cache; tracking modifications to the memory block while in the cache; and writing back the memory block from the cache to the non-volatile memory based on a write back policy that predicts when the memory block is finished being modified. |
