发明名称 6F2 3-transistor DRAM gain cell
摘要 A high density vertical three transistor memory cell is provided. The high density vertical three transistor memory cell is formed in a vertical pillar. The vertical pillar includes a first vertical transfer device having a source region, a drain region, and a body region therebetween on a first side of the vertical pillar. The vertical pillar also includes a second vertical transfer device having a source region, a drain region, and a body region therebetween on a second side of the vertical pillar. A write data wordline opposes the first vertical transfer device. A read data wordline opposes the second vertical transfer device. A storage capacitor is coupled to the drain region of the first vertical transfer device. The storage capacitor further serves as a gate for a third transistor.
