Abstract: In one aspect, a determination is made as whether partition metadata of a solid state memory has changed, and if so, the partition metadata is analyzed to locate invalid data stored in the solid state memory. This analysis may include determining that a file system type of a partition has changed, and invalidating data in response to the changed file system type. Alternately, or in addition, the analysis may include determining that a partition has changed, and invalidating data in response to the changed partition.

Abstract: In one aspect, meta data corresponding to a non-volatile storage media is read from the non-volatile storage media. Meta data to be updated is detected from the read meta data. Based on the read meta data and the detected meta data to be updated, storage areas of the non-volatile storage media are invalidated.

Abstract: A semiconductor memory device includes a nonvolatile memory device having a plurality of physical sectors, and a memory controller configured to translate a logical address received from a host to a physical address, with reference to mapping data that defines a correspondence between the logical address and the physical address. The nonvolatile memory device is configured to access a first physical sector corresponding to the physical address, and, when a data delete command is provided from the host to the memory controller to delete first data that is stored in the first physical sector, the memory controller delays an erase and/or merge operation for the first physical sector in which the first data is stored.
