ADAPTIVE HOST MEMORY BUFFER (HMB) CACHING USING UNASSISTED HINTING |
| 摘要 |
A storage device includes a nonvolatile memory. The storage device further includes a hint derivation module for automatically deriving, from host accesses to the storage device, hints regarding expected future host accesses to a table that maps logical memory addresses to physical memory addresses in the nonvolatile memory. The storage device further includes an adaptive host memory buffer (HMB) caching module for using the hints to identify portions of the table to cache in the HMB and for caching the identified portions in the HMB, which is external to the storage device and accessible by the storage device via a bus. |

1. A storage device comprising:
nonvolatile memory; and a hint derivation module for automatically deriving, from host accesses to the storage device, hints regarding expected future host accesses to a table that maps logical memory addresses to physical memory addresses in the nonvolatile memory; and an adaptive host memory buffer (HMB) caching module for using the hints to identify portions of the table to cache in the HMB and for caching the identified portions in the HMB, which is external to the storage device and accessible by the storage device via a bus. |
