Abstract: A device for preventing current-leakage is located between a transistor and a capacitor of a memory cell. The two terminals of the device for preventing current-leakage are respectively connected with a slave terminal of the transistor and an electric pole of the capacitor. The device for preventing current-leakage has at least two p-n junctions. The device for preventing current-leakage is a lateral silicon controlled rectifier, a diode for alternating current, or a silicon controlled rectifier. By utilizing the driving characteristic of the device for preventing current-leakage, electric charge stored in the capacitor hardly passes through the device for preventing current-leakage when the transistor is turned off to improve the current-leakage problem.
