A semiconductor memory device is provided with: first and second access PMOS transistors formed on N well regions; first and second driver NMOS transistors formed on a P well region; a word line connected to the gates of first and second access PMOS transistors; and first and second bit lines connected to the sources of first and second access PMOS transistors, respectively. Then, N-type diffusion regions and P-type diffusion regions extend in the same direction while polysilicon interconnections extend in the same direction.
