Classification: CPC G | IPC G

Claim 7:
8. The memory device according to claim 1,
wherein the control device determines the program mode corresponding to a second program pulse as one of a first mode, a second mode, and a third mode,
wherein the control device is further configured to apply, in the first mode, the second program pulse to the at least one non-volatile memory cell for changing or adjusting a threshold voltage of the at least one non-volatile memory cell by a first amount which is equal to or larger than an amount caused by the first program pulse,
wherein the control device is further configured to apply, in the second mode, the second program pulse to change or adjust the threshold voltage of the at least one non-volatile memory cell by a second amount which is smaller than the amount caused by the first program pulse, and
wherein the control device is further configured to apply, in the third mode, the second program pulse to the at least one non-volatile memory cell of which a change of the threshold voltage is inhibited.
