Methods and apparatus for dynamically configuring a redundant area of a
physical page are disclosed. According to one aspect of the present
invention, a method for dynamically configuring a redundant area of a
page associated with a physical block of a non-volatile memory of a
memory system includes determining when at least one byte associated with
the redundant area is to be altered. The byte includes error correction
code (ECC) information associated with a first ECC algorithm at the time
of the determination. The method also includes altering the byte when it
is determined that the byte is to be altered. Altering the byte includes
altering the byte to include ECC information associated with a second ECC
algorithm.
