    摘要: An apparatus, system, and method are disclosed for coordinating storage requests in a multi-processor/multi-thread environment. An append/invalidate module generates a first append data storage command from a first storage request and a second append data storage command from a second storage request. The storage requests overwrite existing data with first and second data including where the first and second data have at least a portion of overlapping data. The second storage request is received after the first storage request. The append/invalidate module updates an index by marking data being overwritten as invalid. A restructure module updates the index based on the first data and updates the index based on the second data. The updated index is organized to indicate that the second data is more current than the first data regardless of processing order. The modules prevent access to the index until the modules have completed updating the index.

    摘要: An apparatus, system, and method are disclosed for storing information in a storage device that includes multi-level memory cells. The method involves storing data that is written to the storage device in the LSBs of the multi-level memory cells, and storing audit data in the MSBs of the multi-level memory cells. The audit data can be read separately from the data and used to determine whether or not there has been any unintended drift between states in the multi-level cells. The audit data may be used to correct data when the errors in the data are too numerous to be corrected using error correction code (ECC). The audit data may also be used to monitor the general health of the storage device. The monitoring process may run as a background process on the storage device. The storage device may transition the multi-level memory cells to operate as single-level memory cells.
