Abstract:
The invention discloses a data transfer protection apparatus for a flash memory controller, placed between Bose-Chaudhuri-Hocquenghem (BCH) and NAND Flash Chip. In encode path the hardware module selects a sequence of constant values, exclusive-or the original parity with that constant value. In decode path the hardware module detects the parity period, exclusive-or the parity which is read out from NAND Flash Chip with the same constant value sequence.
