Abstract
A semiconductor memory device of an embodiment includes: a first inverter including a first P-channel and first N-channel transistors; a second inverter including a second P-channel and second N-channel transistors and being cross-connected to the first inverter; a third P-channel transistor; a third N-channel transistor; a first wiring; a second wiring; a third wiring; a fourth wiring; a fifth wiring; a sixth wiring; and a controller that drives the first to sixth wirings. When writing second-level data that is at a higher potential level than first-level data into the drain of the second P-channel transistor and the drain of the second N-channel transistor, the controller puts one of the fifth wiring and the sixth wiring into a floating state.
