A nonvolatile semiconductor memory device is provided with a memory cell array, a judgment potential correction circuit, and a readout circuit. In the memory cell array, a plurality of memory cells are arranged in a matrix form, and the array includes a first memory cell as a readout object and a second memory cell disposed adjacent to the first memory cell. The judgment potential correction circuit corrects a judgment potential based on a threshold value of the second memory cell. The readout circuit reads the first memory cell as the readout object by use of the corrected judgment potential.
