ABSTRACT:
A flash memory system segregates overhead data from user data so that overhead data may be addressed, programmed and erased independently from user data. The non-volatile memory medium of a flash memory system is mapped into a plurality of separately addressable memory blocks that are independently programmable and independently erasable, including a plurality of Dedicated Overhead Blocks and Dedicated Data Blocks. The Dedicated Overhead Blocks are mapped according to a plurality of distinguishably addressable segments, and include a first Dedicated Overhead Block and a second Dedicated Overhead Block. User Data defined by a VLBA is stored in a Dedicated Data Block within the flash memory.
