Abstract
PURPOSE:To reduce the number of wiring lines and highly integrate a semiconductor storage device by setting the threshold of a transferring transistor of each storage part to a different value and driving the transistor through a common word line. CONSTITUTION:One of the sources and drains of respective transferring transistors T1, T2... is connected to corresponding storing parts m1, m2... and the other is connected to a bit line B in common. The gates of these transistors T1, T2... are connected to a word line W in common. The thresholds of the transistors T1, T2 are set to different values respectively to select a required storage part out of the parts m1, m2.... Since the plural memory cells are controlled by the common word line and read/written by the common bit line, the number of wiring lines is reduced and the semiconductor storage device can be highly integrated.
