The semiconductor device is formed using a memory cell including a wide band gap semiconductor such as an oxide semiconductor. The semiconductor device includes a potential change circuit having a function of outputting a potential lower than a reference potential for reading data from the memory cell. When the wide band gap semiconductor which allows a sufficient reduction in off-state current of a transistor included in the memory cell is used, a semiconductor device which can hold data for a long period can be provided."},"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 provide a semiconductor device with a novel structure, which can hold stored data even when power is not supplied and which has an unlimited number of write cycles.
