Abstract

In the programming of a non-volatile memory device, such as a NAND flash memory device 100, a positive bias voltage V.sub.bias is applied to a bit line 44 to set a respective memory gate 44a in a programmed state. In a further embodiment, the positive bias voltage V.sub.bias is obtained by dividing the select drain gate voltage V.sub.cc using two resistors 56 and 58 connected in series.
