Abstract
A bias voltage generator for providing a control voltage and a source line voltage to a memory array includes a reference voltage generating circuit and a voltage converting circuit. The reference voltage generating circuit receives a program signal or an erase signal, and generates a reference voltage. If the program signal is received by the reference voltage generating circuit, the reference voltage has a positive temperature coefficient. If the erase signal is received by the reference voltage generating circuit, the reference voltage has a negative temperature coefficient. The voltage converting circuit converts the reference voltage into the control voltage and the source line voltage. The voltage converting circuit enlarges the reference voltage by a first magnification so as to produce the source line voltage, and enlarges the reference voltage by a second magnification so as to produce the control voltage.
