A device may comprise a plurality of non-volatile memories configured to store a plurality of physical pages and a controller coupled thereto, configured to program and read data to and from the plurality of memory devices. The data may be stored in a plurality of logical pages (L-Pages) of non-zero length at starting addresses within the plurality of physical pages and execute first and second commands to indicate that first and second physical locations within the plurality of non-volatile memories no longer contains valid data and are now free space. This may be done by carrying out first and second virtual write operations of first and second L-Pages of a predetermined length at first and second unique addresses within a virtual address range that does not correspond to any of the physical pages, and accounting for an amount of free space gained as a result of executing the commands. |
