The first transistor has higher switching speed than the second transistor. The first transistor, the second transistor, and the capacitor are electrically connected in series. Accumulation of charge in the capacitor and release of charge from the capacitor are performed through the first transistor and the second transistor. In this manner, the power consumption of the semiconductor device can be reduced and data can be written and read at higher speed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device and driving method of semiconductor device","description":"A memory cell includes a capacitor, a first transistor, and a second transistor whose off-state current is smaller than that of the first transistor.
