In some examples, a main word line driver may include a transistor that is driven between an on state and a high resistance state by a signal based, at least in part, on a row address. In both states, the transistor may maintain a main word line in an inactive state. When in the high resistance state, the transistor may be overridden by a decoder that drives the main word line to an active state. In some examples, a main word line driver may include a transistor maintained in a high resistance state coupled in parallel with another transistor that may be driven between an on state and an off state by a signal based, at least in part, on a row address. When the other transistor is in the off state, the high resistance state transistor may be overridden by a decoder that drives a main word line to an active state.
