ABSTRACT:
A semiconductor memory device includes a memory cell array comprised of a plurality of memory cells each having a single transfer transistor and a single capacitor and a peripheral circuit including a plurality of drive transistors and adapted to drive the memory cell. The source and drain regions of the transfer transistor have an impurity concentration lower in level than that of the source and drain regions of the drive transistor.
