The sense amplifier circuit includes a cross-coupled first transistor and second transistor that perform amplification. The sources of the cross-coupled transistors are respectively connected in series with a third transistor and a fourth transistor, and electrical current supply capability of the third and fourth transistors is controlled by a control voltage given to control electrodes of the third and fourth transistors. In a data retaining period, a minimum sub-threshold current necessary for retaining the data is flowed to the third and fourth transistors according to the control voltage, and bit line potential is maintained."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device","description":"A semiconductor device includes a sense amplifier circuit.
