Abstract
A data storage device may comprise a flash controller and an array of flash memory devices coupled to the flash controller. The array may comprise a plurality of S-Pages that may each comprise a plurality of F-Pages. In turn, each of the plurality of F-Pages may be configured to store a variable amount of data and a variable amount of error correction code. The flash controller may be configured to generate an error correction code across each F-Page of an S-Page and to store the generated error correction code within one or more F-Pages having the largest amount of data.
