The first memory cell has a first transistor that is coupled to a first word line, a first source line, and a bit line. The second memory cell has a second transistor that is coupled to a second word line, a second source line, and the bit line. The dummy transistor has the same structure as the first transistor and is coupled to a dummy word line, a dummy source line, and a dummy bit line. When a predetermined voltage for writing data into the first memory cell is to be applied to the first word line, the voltage control circuit couples the dummy bit line to the second source line and applies the predetermined voltage to the first dummy word line."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor memory device","description":"A semiconductor memory device according to the present invention includes a first memory cell, a second memory cell, a dummy transistor, and a voltage control circuit.
