    • PURPOSE: A nonvolatile semiconductor memory device and its programming method and its erasing method are provided to suppress the generation of disturbance and to achieve large integration easily. CONSTITUTION: According to the nonvolatile semiconductor memory device, a word line voltage applying circuit(7) selects the first word line voltage and then applies it to a selected word line connected to a selected memory cell programmed or erased, and selects the second word line voltage and then applies it to non-selected word lines except the selected word line, during programming or erasing operation. A bit line voltage applying circuit(6) selects the first bit line voltage and then applies it to a selected bit line connected to a selected memory cell programmed or erased, and selects the second bit line voltage and then applies it to non-selected bit lines except the selected bit line, during programming or erasing operation.
    • 目的:提供一种非易失性半导体存储器件及其编程方法及其擦除方法,以抑制干扰的产生并实现大集成。 构成:根据非易失性半导体存储器件,字线电压施加电路(7)选择第一字线电压,然后将其施加到与所选择的被编程或擦除的存储单元相连的选定字线上,并选择第二字线 电压,然后在编程或擦除操作期间将其应用于除选定字线以外的未选择的字线。 位线电压施加电路(6)选择第一位线电压,然后将其施加到连接到所选存储单元编程或擦除的选定位线,并选择第二位线电压,然后将其施加到未选择的位 在编程或擦除操作期间除所选位线以外的线。
