IPC: G11C11/408
Filed: 2000-04-13
Abstract: PROBLEM TO BE SOLVED: To provide a highly reliable semiconductor memory to which low power source voltage is applied. SOLUTION: In a word driver 1 of a DRAM, a N channel MOS transistor QN3 to the gate of which a power source potential Vcc is applied is connected between a gate of a P channel MOS transistor QP1 for pull-up and a gate of a N channel transistor QN1 for pull-down. Even when the voltage of an input signal ZMWL turns to a high potential Vpp', the voltage of a gate of the N channel MOS transistor QN1 is kept to the power source potential Vcc from which threshold voltage Vthn of the N channel MOS transistor QN3 has been subtracted. Therefore, voltage applied to a gate insulation film of the N channel MOS transistor QN1 is lower than that of a conventional device, thereby reliability of the N channel MOS transistor QN1 is improved.
