Abstract:
According to an embodiment, a semiconductor memory device includes a plurality of word lines, a plurality of bit lines, a plurality of memory cells, a word line driving circuit, a sense amplifier circuit, and a controller. The memory cell connected to the selected word line is written with data using a write sequence including a plurality of write loops each including a write operation of applying a write voltage to the selected word line by the word line driving circuit and a verify operation of detecting data of the memory cell by the sense amplifier circuit. The controller determines an (n+k)-th (where n is an integer not less than 1 and k is an integer not less than 2) verify operation based on comparison between an n-th verify operation and an (n+1)-th verify operation in the write sequence.

Claim (Index 13):
The device according to  claim 9 ,\n wherein the write sequence includes a first write sequence and a second write sequence different from the first write sequence in a distribution of the threshold voltage after the first write sequence is executed, the controller executes the n-th and (n+1)-th verify operations at the first verify level of the threshold voltage in the verify operation of the second write sequence, and based on a difference between the number of memory cells passing the n-th verify operation at the first verify level of the threshold voltage and the number of memory cells passing the (n+1)-th verify operation at the first verify level of the threshold voltage, the controller determines whether the (n+k)-th verify operation at the second verify level of the threshold voltage which is a verify level higher than the first verify level of the threshold voltage is executed or omitted.
