FIG. 4 illustrates how one example of a gray code encoding maps to the memory states. Below each memory state is a binary value of 4 bits listed from the most significant bit (MSB) reading down to the least significant bit (LSB). FIG. 5 illustrates the same encoding mapping in a table form. A page of data, logical or physical is associated with each position in the binary value. In other words, reading all MSB bits of memory cells along a physical word line, a physical page, or groups of physical pages along a row of the non-volatile memory array forms a logical page.
