    • PURPOSE: A semiconductor device is provided to sufficiently reduce an off current by using a semiconductor with a large band gap. CONSTITUTION: A bit line control transistor(108) is serially inserted into a bit line(104). The minimum potential of a gate of the bit line control transistor becomes sufficient negative value. The gate of the bit line control transistor is connected to a bit line control circuit(109) connected to a battery. The minimum potential of the bit line is higher than the minimum potential of the word line. The outflow of charges accumulated in the bit line is prevented by blocking the bit line due to the bit line control transistor when power is not supplied from the outside.
