Abstract:
1. A method for storing data within a non-volatile memory comprised of a plurality of blocks in an array formed on a semiconductor substrate, each of the plurality of blocks having an indicator indicative of whether the block is a reclaimed block, the method comprising: identifying a first block of the plurality of blocks into which the data is to be stored; responsive to the indicator associated with the first block meeting a criterion, encoding the data using a first error detection algorithm; then writing the encoded data into the first block; identifying a second block of the plurality of blocks into which data is to be stored; responsive to the indicator associated with the second block not meeting the criterion, encoding the data using a second error detection algorithm, the second error detection algorithm having a higher error detection capability than the first error detection algorithm; and then writing the encoded data into the second block.
