A voltage level shift circuit includes a first stage which receives an input signal having voltage levels Vcc and Vss, where Vcc>Vss, and which outputs complementary first and second intermediate signals, wherein the complementary first and second intermediate signals have voltage levels VI<SUB>high </SUB>and VI<SUB>low</SUB>, where VI<SUB>high</SUB>>VI<SUB>low</SUB>; and a second stage which receives the first and second intermediate signals, and which outputs complementary first and second output signals, wherein the complementary first and second output signals have voltage levels VO<SUB>high </SUB>and VO<SUB>low</SUB>, where VO<SUB>high</SUB>>VO<SUB>low</SUB>, wherein VI<SUB>high</SUB>>VO<SUB>high </SUB>or VI<SUB>low</SUB><VO<SUB>low</SUB>, and wherein VO<SUB>high</SUB>>Vcc and VO<SUB>low</SUB><Vss.
