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.

摘要： An apparatus, system, and method are disclosed for persistently storing data objects. An object store index module maintains an object store. The object store associates each data object of a plurality of data objects with a unique key value. A storage module persists object store data defining the object store to a logical block address of the solid-state storage device in response to an update event. The logical block address is a member of a restricted set of logical block addresses. The logical block address is mapped to a location of the object store data on the solid-state storage device. A read module provides a requested data object from the plurality of data objects to a requesting client in response to receiving a read request for the requested data object from the requesting client. The read request comprises the key value associated with the requested data object.
