Abstract
A semiconductor memory device includes word lines, bit lines, and memory cells at intersections of the word lines and the bit lines. A driver is configured to a voltage to a selected word line. A sense amplifier is configured to detect data of the memory cells. A controller is configured to control the driver and the sense amplifier. A writing sequence of writing data to a selected memory cell connected to the selected word line includes a plurality of writing loops including a write operation and a verify operation. The controller is configured to perform the write operation on the selected memory cell a predetermined number of times corresponding to write data to be written to the selected memory cell, without the verify operation, after a threshold voltage of the selected memory cell connected to the selected word line reaches a first level.
