Abstract
A load circuit for compensating for source side loading effects in a non-volatile memory. Specifically, embodiments of the present invention describe a reference cell that is coupled to a plurality of load circuits. At least one of the plurality of load circuits, an mth load circuit, comprises a select transistor coupled to m resistors that are coupled in series. The mth load circuit matches a source side loading effect of a corresponding mth memory cell located m memory cells away from a source line node on a source line coupling source regions in memory cells of a row of memory cells.
