Means for Solving the Problems: In anon-volatile semiconductor memory device, comprising:a non-volatilememory array, which stores multi-valued states by settinga plurality of different threshold voltages to correspond to a pluralityof states to each memory cell; and a control circuit, which controlsprogramming to the memory cell array, when increasing the programmingvoltage from a predetermined programming start voltage by a predeterminedvoltage increment gradually and verifying it at the same time forprogramming the memory cell, the control circuit determines and sets theprogramming start voltage for programming according to a programming pulsenumber at the moment the verifying process passes in the precedingprogramming.
