Paragraph Number

18

The apparatuses and systems disclosed herein may further comprise an index comprising mappings between logical identifiers and physical addresses on the non-volatile storage medium, wherein the marking module is configured to remove a mapping between the logical identifier and the physical addresses of the data from the index. The marking module may be further configured to delete a reference to the physical address from an index entry of the logical identifier. Removal of the mapping may indicate that data stored at the physical address can be erased from the non-volatile storage medium.
