Abstract
A method of storing data includes receiving data including a first group of bits and a second group of bits and initiating a shaping encoding operation on the second group of bits to generate a third group of bits. The third group of bits has more bits than the second group of bits. The shaping encoding operation is configured to produce a non-uniform probability distribution of bit values in the third group of bits. The first group of bits and first error correction coding (ECC) parity bits corresponding to the first group of bits are stored to a first logical page that is within a physical page of a MLC memory and the third group of bits and second ECC parity bits corresponding to the third group of bits are stored to a second logical page that is within the physical page of the MLC memory.
