Abstract: A memory device includes a first bit line configured to supply a first bit line bias voltage, a memory cell transistor having a first operating voltage, a selection transistor having a second operating voltage and configured to control the supply of the first bit line bias voltage to a source of the memory cell transistor, and a second bit line connected to a drain of the memory cell transistor. A level of the first operating voltage is about equal to a level of the second operating voltage.

Abstract: A semiconductor device includes a substrate, a gate structure, source and drain regions, and first and second lightly doped drain (LDD) regions. The source and drain regions are spaced apart and formed in an active region of the substrate at opposite sides of the gate structure. The first LDD region surrounds one side surface and a bottom surface of the drain region and has a first junction depth. The second LDD region surrounds one side surface and a bottom surface of the source region and has a second junction depth less than the first junction depth. The gate structure includes a gate dielectric layer, a gate electrode, and gate spacers respectively disposed on opposite side walls of the gate dielectric layer and the gate electrode. One side wall of the gate dielectric layer and electrode is aligned with one side surface of the first LDD region.
