Abstract: A word line driver circuit for a semiconductor memory device. One or more transistors in the driver circuit are fabricated such that they are susceptible, under certain conditions, to gate-induced diode leakage (GIDL). One terminal of the transistors are coupled to a local supply node, which during standby conditions when the word line driver circuit is not driving a word line, is maintained at a voltage less than that of a global power supply node. In one embodiment, the local power supply node is coupled to the global power supply node by means of at least one decoupling transistor receiving a control signal at its gate and by a vt-connected transistor, such that the voltage on the local power supply node is maintained at a level not exceeding one transistor threshold voltage less than the global power supply node voltage when the decoupling transistor is off.
