Zusammenfassung:Apparatus and methods are disclosed, including receiving an indication to selectively overwrite first data stored on a first page of a first subset of a group of multi-level memory cells of a storage system, determining a second subset of memory cells from the first subset that, in response to programming from a first level to a second level, will alter a read output of the first data on the first page and maintain a read output of remaining pages, and programming the second subset of memory cells from the first level to the second level to securely remove the first data stored on the first page while maintaining data on the remaining pages.
