Abstract
A semiconductor memory device that includes a memory cell connected to a wordline and a wordline voltage generator. The wordline voltage generator supplies a first negative voltage to the wordline in a standby state and supplies a second negative voltage that is lower with respect to ground than the first negative voltage to the wordline in a refresh operation. Accordingly, a leakage current generated at a transistor of a memory cell by gate-induced drain leakage (GIDL) is suppressed to enhance the performance of a refresh operation.
