Abstract:
A semiconductor memory device includes memory cells connected to word lines and bit lines. In a verification operation, a controller applies first and second verification voltages to a word line in sequence, a first voltage to a first bit line of a first cell and a second voltage to second bit line during first level verification, and, if the first cell passes first voltage level verification, the first voltage is then applied to both the first and second bit lines while the second verification voltage is applied to the word line.

Claim (Index 13):
The semiconductor memory device according to  claim 9 , wherein\n the plurality of memory cells store fourth data values for the multiple bits according to a fourth threshold voltage lower than the first threshold voltage, each of the plurality of sense amplifier units further includes a second latch circuit that stores write data corresponding to a first bit of the multiple bits and a third latch circuit that stores write data corresponding to a second bit of the multiple bits, and the controller is configured to, during the verification operation: while applying the first verification voltage to the word line, store a verification result of the first memory cell, in the first latch circuit of the corresponding sense amplifier unit, and while applying the second verification voltage to the word line, store data for the first and second bits of the fourth data values in the second and third latch circuits.
