ABSTRACT:
A semiconductor memory device including a first MIS transistor having source and drain regions formed in a substrate and a gate electrode provided on the substrate through an insulating layer; a semiconductor layer provided on the first MIS transistor through the insulating layer and being in contact with the source and drain regions of the first MIS transistor; a second MIS transistor having source and drain regions formed in the semiconductor layer and being in contact with the source and drain regions of the first MIS transistor and having a gate electrode provided on the semiconductor layer through an insulating layer; and a bit line being in contact with the source or drain region of the second MIS transistor and extended on the second MIS transistor; each gate electrode of the first and the second MIS transistors being connected with different word lines respectively, and impurities having an amount more than a required value being doped to at least one of the substrate and the semiconductor layer below the gate electrode of the first MIS transistor and the semiconductor.
