A bit line controlling transistor is inserted in a bit line in series. The minimum potential of a gate of the transistor is set to a sufficiently negative value. The gate of the transistor is connected to a bit line controlling circuit connected to a battery. The minimum potential of the bit line is set higher than that of a word line. When power from an external power supply is interrupted, the bit line is cut off by the transistor, ensuring prevention of outflow of charge in the bit line. The potential of a source or a drain (bit line) of a cell transistor is sufficiently higher than that of a gate of the cell transistor, resulting in an absolute off-state; thus, data can be retained. Other embodiments are disclosed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device","description":"An object is to increase the retention characteristics of a memory device formed using a wide bandgap semiconductor.
