A semiconductor memory device may be formed from a pair of transfer MOS transistors 1, 2 controlled by a word line 11 and a pair of data retaining flip-flop circuit formed from serially connected load elements 5, 6 and drive MOS transistors 3, 4. In the semiconductor memory device, the transfer MOS transistors 1, 2 have a threshold voltage greater than a threshold voltage of the drive MOS transistors 3, 4. The memory device may display an improved beta ratio, and reduce the size of the drive MOS transistors to thereby reduce the cell area.
