Abstract
A semiconductor memory device including a plurality of level converters, each of the level converters including a bridge circuit constituted by four MOS transistors having one type of conductivity, gates of one pair of four transistors opposing each other receiving a first signal and gates of the other pair of four transistors opposing each other receiving a signal complementary to the first signal; a pair of complementary MOS inverter circuits to which a second signal and a signal complementary to the second signal are input, respectively, the outputs of the pair of inverter circuits being connected to a first pair of connecting points positioned alternately in the bridge circuit, respectively; and a flip-flop circuit connected between a second pair of connecting points positioned alternately in the bridge circuit, to thereby output a third signal and a signal complementary to the third signal from the second pair of connecting points, resepctively.
