A method includes the steps of storing non-header data into a plurality of logical pages (“Lpages”) of a non-volatile memory (“NVM”), each Lpage including a number of read units, wherein at least one of the read units is a spanning read unit that spans Lpage boundaries and includes a first byte of at least one Lpage starting in the read unit, storing, in each of the at least one spanning read units that include the first byte of the at least one Lpage starting in the read unit, an Lpage identification header per each of the at least one Lpages starting in the spanning read unit, each Lpage identification header identifying a location of the first byte of the respective Lpage starting within the respective spanning read unit, and locating an Lpage of data stored in the NVM by referring to an entry stored a flash memory controller map table.
