Systems and methods are provided for handling temporary data that is stored in a non-volatile memory, such as NAND flash memory. The temporary data may include hibernation data or any other data needed for only one boot cycle of an electronic device. When storing the temporary data in one or more pages of the non-volatile memory, the electronic device can store a temporary marker as part of the metadata in at least one of the pages. This way, on the next bootup of the electronic device, the electronic device can use the temporary marker to determine that the associated page contains unneeded data. The electronic device can therefore invalidate the page and omit the page from its metadata tables.
