A semiconductor memory device comprises a memory cell, first and second voltage generating circuits generating first and second voltages, and a control circuit. A memory element and a diode included in the memory cell are connected in series between first and second lines. The first voltage has no temperature dependence, and the second voltage has a temperature dependence opposite to that of a forward voltage of the diode. The control circuit detects a resistance state of the memory element in accordance with a change in current flowing in the memory cell in a state where the first/second voltage is applied to the first/second in a read operation of the memory cell. |
