Abstract:
According to one embodiment, a semiconductor memory device includes a memory cell having a variable resistance unit, a first selector, and a second selector. The first and second selectors are connected in series with the variable resistance unit and have different switching characteristics from one another. A control unit is provided to write data to the memory cell by setting a resistance state of the variable resistance unit and to read data from the memory cell according to the resistance state of the variable resistance unit.
