Abstract:
A semiconductor memory device includes a first memory cell transistor, a second memory cell transistor, and a third memory cell transistor that are connected in series. A word line is coupled to a gate of the third memory cell transistor. A controller is configured to set a first upper limit value for voltages applied to the word line during writing of data to the first memory cell transistor and a second upper limit value for voltages applied to the word line during writing of data to the second memory cell transistor. The second upper limit value is different from the first upper limit value.

Claim (Index 9):
A semiconductor memory device, comprising:\n a first memory cell connected to a first bit line, a gate of the first memory cell being connected to a first word line; a second memory cell connected to the first bit line, a gate of the second memory cell being connected to a second word line; a third memory cell connected to the first bit line, a gate of the third memory cell being connected to a third word line, a first selection transistor connected to the first bit line; a second selection transistor connected to the first bit line, the first, second, and third memory cells being between the first and second selection transistors along the first bit line; a controller configured:\n to step up a program voltage during a data writing operation in first increments, the program voltage being applied to a selected word line during the data writing operation, and \n to step up a first pass voltage during the data writing operation in second increments up to a first upper limit value, the first pass program voltage being applied to at least one non-selected word line during the data writing operation, wherein \n the first upper limit value is set by the controller to a first value when the selected word line is the first word line and to a second value different from the first value when the selected word line is the second word line.
