摘要： To provide a semiconductor memory device capable of storing multi-value data while suppressing an increase in the threshold voltage set for a memory cell. A semiconductor memory device according to an embodiment includes a plurality of memory cell pairs, each having a first memory cell and a second memory cell. The first memory cell is configured so as to set at least one threshold voltage, whereas the second memory cell is configured so as to set a plurality of threshold voltages. Data stored in the memory cell pairs is defined using differences between the threshold voltages of the second memory cell and the threshold voltage of the first memory cell.

摘要： On a semiconductor substrate, coils CL5 and CL6 and pads PD5, PD6, and PD7 are formed. The coil CL5 and the coil CL6 are electrically connected in series between the pad PD5 and the pad PD6, and the pad PD7 is electrically connected between the coil CL5 and the coil CL6. The coil magnetically coupled to the coil CL5 is formed just below the coil CL5, the coil magnetically coupled to the coil CL6 is formed just below the coil CL6, and they are connected in series. When a current is flowed in the coils connected in series formed just below the coils CL5 and CL6, directions of induction current flowing in the coils CL5 and CL6 are opposed to each other in the coils CL5 and CL6.
