Abstract
According to one embodiment, a semiconductor memory device comprises a first bank and a second bank. Each of the first bank and the second bank comprises a memory cell having a variable resistor element, a reference cell, a sense amplifier having a first input terminal electrically coupled to the memory cell and a second input terminal electrically coupled to the reference cell, and a first transistor electrically coupling the memory cell and the first input terminal of the sense amplifier. A gate of the first transistor of the first hank and a gate of the first transistor of the second bank are independently supplied with a voltage.
