    • A charge pump circuit of a semiconductor memory device provides high efficiency. A high voltage detector outputs a high voltage detection signal. A regulator outputs a high level and a controller is triggered at a descent edge of a row access strobe bar signal and outputs a high level row access strobe bar pulse signal. An oscillator generates an oscillation pulse signal in accordance with the high level turn-on signal outputted from the regulator. A charge pump performs a pumping operation until the oscillation pulse signal reaches a potential of (Vdd+2Vt) when the oscillation pulse signal is applied thereto, and halts the pumping operation when the high level high voltage detection signal is applied. A pull-up transistor precharges the raised voltage Vpp to a potential of (Vdd-Vt) when power is turned on. The circuit enables a charge pump to have a double booster and a pumping capacitor, thereby satisfying a fast charge supply at a low level voltage and to supply an appropriate amount of charge at a high level voltage.

    • Compound tunneling field effect transistors integrated on a silicon substrate are provided with increased tunneling efficiency and an abrupt band slope by forming a source region with a material having a bandgap at least 0.4 electron volts (eV) narrower than that of silicon to increase a driving current (ON current) by forming a channel region with a material having almost no difference in lattice constant from a source region and having a high electron mobility at least 5 times higher than silicon. ON/OFF current ratio simultaneously is increased by forming a drain region with a material having a bandgap at least as wide as a channel region material to restrain OFF current. Tunneling field effect transistors having various threshold voltages according to circuit designs are formed easily by adding a specific material with an electron affinity less than a source region material when forming a channel region.
