Abstract:
According to one embodiment, a semiconductor memory device includes memory cells, a word line, bit lines, and a controller. The word line is connected to the memory cells. Each of the lines is connected to the memory cells. In a program operation, while applying a program voltage to the word line, the controller applies a first voltage to a bit line connected to memory cells to which a first data is to be written, applies a second voltage lower than the first voltage to a bit line connected to memory cells to which a second data is to be written, and applies a third voltage lower than the second voltage to a bit line connected to memory cells to which a third data is to be written.

Claim (Index 1):
A semiconductor memory device comprising:\n a plurality of memory cells each configured to store a plurality of bits of data based on a threshold voltage and to be set to have a first threshold voltage in a case of storing first data as the plurality of bits of data, set to have a second threshold voltage higher than the first threshold voltage in a case of storing second data as the plurality of bits of data, and set to have a third threshold voltage higher than the second threshold voltage in a case of storing third data as the plurality of bits of data; a word line connected to a plurality of the memory cells; a plurality of bit lines each connected to the plurality of the memory cells; and a controller configured to perform a write including a program loop including a program, wherein the controller applies a first program voltage to the word line in the program, and while applying the first program voltage, applies the first voltage to bit lines connected to memory cells to which the first data is to be written, applies a second voltage lower than the first voltage to bit lines connected to memory cells to which the second data is to be written, and applies a third voltage lower than the second voltage to bit lines connected to memory cells to which the third data is to be written.
