Abstract

PURPOSE:To eliminate blooming and smear phenomenon, by injecting bias charge to bit lines and electrodes connected to them, and absorbing it in a drain of a control electrode, through the drain taken as an input. CONSTITUTION:A bit line 27, electrode 28 of MOSBUFF1, electrode 29 of MOSBUFF2, electrode 30 of MOSLR, and drain 31 of MOSLR are located on a substrate 26. At a time t=t1 of horizontal erase period, the part beneath the electrode 30 is taken as a barrier region, that beneath the electrode 29 is taken as storage region and a bias charge 46 is stored. The MOSLR is made non-conductive, the applied voltage to the MOSBUFF2 is lowered and the bias charge is injected to the bit line 27. The applied voltage of the MOSBUFF2 is restored to the state at t=t1 to conduct the MOSLR, and the unnecessary charge 46 left on the bit line is absorbed in the drain of the MOSLR. Thus, blooming and smear phenomenon are prevented.
