Abstract:
A static random access memory (SRAM) device includes an inverter including a ninth first-conductivity-type semiconductor layer formed on a semiconductor substrate; a first pillar-shaped semiconductor layer which is formed on the semiconductor substrate and in which a first first-conductivity-type semiconductor layer, a first body region, a second first-conductivity-type semiconductor layer, a first second-conductivity-type semiconductor layer, a second body region, and a second second-conductivity-type semiconductor layer are formed from the substrate side in that order; a first gate insulating film formed around the first body region; a first gate formed around the first gate insulating film; a second gate insulating film formed around the second body region; a second gate formed around the second gate insulating film; and a first output terminal connected to the second first-conductivity-type semiconductor layer and the first second-conductivity-type semiconductor layer.
