    • A memory device having one transistor and one resistant element as a storing means and a method for driving the memory device, includes an NPN-type transistor formed on a semiconductor substrate, an interlayer insulating film formed on the semiconductor substrate to cover the transistor in which a contact hole exposing a source region of the transistor is formed, a resistant material in which a bit data “0” or “1” is written connected to the source region of the transistor by a conductive plug or an insulating film, and a conductive plate contacting the resistant material. The memory device exhibits improved degree of integration, reduced current consumption by lengthening a refresh period thereof, and enjoys simplified manufacturing process due to a simple memory cell structure.
    • 具有一个晶体管和一个电阻元件作为存储装置的存储器件和用于驱动存储器件的方法包括形成在半导体衬底上的NPN型晶体管,形成在半导体衬底上以覆盖晶体管的层间绝缘膜, 形成暴露晶体管的源极区域的接触孔,通过导电插塞或绝缘膜将位数据“0”或“1”写入的电阻材料连接到晶体管的源极区域,并且导电 板接触抵抗材料。 存储器件通过延长其刷新周期而呈现出提高的集成度,降低的电流消耗,并且由于简单的存储单元结构而享有简化的制造工艺。
