| 20080253185 | Non-Volatile Memory and Method with Control Gate Compensation for Source Line Bias Errors - Source line bias is an error introduced by a non-zero resistance in the ground loop of the read/write circuits. During sensing the source of a memory cell is erroneously biased by a voltage drop across the resistance and results in errors in the applied control gate and drain voltages.
