Content
In one embodiment, for NAND flash media 122 or the like, a binary zero may be represented by a voltage below a read voltage threshold and a binary one may be represented by a voltage above the read voltage threshold. In one example, a data set may be stored with a known bias of 0.5, representing that the expected balance/bias of the data set should be one half binary ones, or DC balanced. In this example, the data set may be read from the storage cells and may gave a read balance/bias of 0.7, meaning that seventy percent of the data bits are binary ones. To determine the direction of deviation, in one embodiment, the DC balance module 404 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 (e.g., “0.2”), the sign of the result (e.g., “positive”), a relationship (e.g., “greater than”), a direction, (e.g., “up”), or another indicator that represents the difference between the expected bias of 0.5 and the read bias of 0.7.
