Paragraph Number

207

In one embodiment, a binary zero is represented by a voltage below the read voltage threshold and a binary one is represented by a voltage above the read voltage threshold. In one example, a data set is stored with a known bias of 0.5, representing that the expected bias of the data set should be one half binary ones, or DC balanced. In this example, the data set is read from the storage cells and the data set has a read bias of 0.7, meaning that seventy percent of the data bits are binary ones. To determine the direction, in one embodiment, the direction module 406 subtracts the expected bias, 0.5, from the read bias of the data set, 0.7, for a direction of 0.2. The direction may be the entire result (i.e. “0.2”), the sign of the result (i.e. “positive”), a relationship (i.e. “greater than”), a direction, (i.e. “up”), or another indicator that represents the difference between the expected bias of 0.5 and the read bias of 0.7.
