Claim 6:
7. The semiconductor memory device of claim 5, wherein:
the second select element includes a seventh select transistor and an eighth select transistor in series,
the fourth select element includes a ninth select transistor and a tenth select transistor in series,
a threshold voltage of the seventh select transistor is larger than a threshold voltage of the ninth select transistor,
a threshold voltage of the eighth select transistor is smaller than a threshold voltage of the tenth select transistor, and
when reading the data of the second memory cell, the control circuit is configured to apply a third voltage different from the first voltage and the second voltage to a gate of the seventh select transistor, a gate of the eighth select transistor, a gate of the ninth select transistor, and a gate of the tenth select transistor.
