    • A non-volatile semiconductor memory device includes a memory cell array and a control circuit. A control circuit performs an erase operation providing a memory cell with a first threshold voltage level for erasing data of a memory cell, and then perform a plurality of first write operations providing a memory cell with a second threshold voltage level, the second threshold voltage level being higher than the first threshold voltage level and being positive level. When the control circuit receives a first execution instruction from outside during the first write operations, the first execution instruction being for performing first function operation except for the erase operation and the first write operations, the circuit performs the first function operation during the first write operations.

    • In writing, a first write operation to a first memory cell is executed; and a second write operation for providing a first threshold-voltage distribution to a second memory cell adjacent to the first one, is executed. The first threshold voltage distribution is a lowest threshold-voltage distribution among the positive threshold voltage distributions. It is verified whether a desired threshold voltage distribution has been obtained in the first memory cell or not (first write verify operation), moreover, it is verified whether a first threshold voltage distribution or a threshold voltage distribution having a voltage level larger than the first threshold-voltage distribution has been obtained in the second memory cell or not (second write verify operation). A control circuit outputs results of the first write verify operation and the second write verify operation.
    • 在写入时,执行对第一存储单元的第一写入操作; 并且执行用于向与第一阈值电压分布相邻的第二存储单元提供第一阈值电压分布的第二写入操作。 第一阈值电压分布是正阈值电压分布中的最低阈值电压分布。 验证在第一存储器单元中是否已经获得期望的阈值电压分布(第一写入验证操作),此外,验证第一阈值电压分布或具有大于第一存储器单元的电压电平的阈值电压分布 在第二存储器单元中已经获得阈值电压分布(第二写入验证操作)。 控制电路输出第一写入验证操作和第二写入验证操作的结果。
