Disclosed is a bit line driver current switch with a constant current source independent of temperature and power supply. Also, the differential between selected and unselected bit voltages is independent of temperature and power supply. This circuit also allows a more negative bit line potential, eliminating potential saturation problems of the bit current switch transistors.
