    • A nonvolatile memory device includes a string selection transistor, a plurality of memory cell transistors, and a ground selection transistor electrically connected in series to the string selection transistor and to the pluralities of memory cell transistors. First impurity layers are formed at boundaries of the channels and the source/drain regions of the memory cell transistors. The first impurity layers are doped with opposite conductivity type impurities relative to the source/drain regions of the memory cell transistors. Second impurity layers are formed at boundaries between a channel and a drain region of the string selection transistor and between a channel and a source region of the ground selection transistor. The second impurity layers are doped with the same conductivity type impurities as the first impurity layers and have a higher impurity concentration than the first impurity layers.
    • 非易失性存储器件包括串选择晶体管,多个存储单元晶体管和与串选择晶体管和多个存储单元晶体管串联电连接的接地选择晶体管。 在存储单元晶体管的沟道和源极/漏极区的边界处形成第一杂质层。 相对于存储单元晶体管的源/漏区,第一杂质层掺杂有相反导电类型的杂质。 第二杂质层形成在串选择晶体管的沟道和漏极区之间的边界处,并且在地选择晶体管的沟道和源极区之间形成。 第二杂质层掺杂有与第一杂质层相同的导电类型杂质,并且具有比第一杂质层更高的杂质浓度。

    • Methods of operating a charge trap nonvolatile memory device include operations to erase a first string of nonvolatile memory cells by selectively erasing a first plurality of nonvolatile memory cells in the first string and then selectively erasing a second plurality of nonvolatile memory cells in the first string, which may be interleaved with the first plurality of nonvolatile memory cells. This operation to selectively erase the first plurality of nonvolatile memory cells may include erasing the first plurality of nonvolatile memory cells while simultaneously biasing the second plurality of nonvolatile memory cells in a blocking condition that inhibits erasure of the second plurality of nonvolatile memory cells. The operation to selectively erase the second plurality of nonvolatile memory cells may include erasing the second plurality of nonvolatile memory cells while simultaneously biasing the first plurality of nonvolatile memory cells in a blocking condition that inhibits erasure of the first plurality of nonvolatile memory cells.
    • 操作电荷阱非易失性存储装置的方法包括通过选择性地擦除第一串中的第一多个非易失性存储单元,然后选择性地擦除第一串中的第二多个非易失性存储单元来擦除第一串非易失性存储单元的操作, 其可以与第一多个非易失性存储器单元交错。 选择性地擦除第一多个非易失性存储单元的操作可以包括擦除第一多个非易失性存储单元,同时在禁止擦除第二多个非易失性存储单元的阻塞条件下同时偏置第二多个非易失性存储单元。 选择性地擦除第二多个非易失性存储单元的操作可以包括擦除第二多个非易失性存储单元,同时在禁止擦除第一多个非易失性存储单元的阻塞条件下同时偏置第一多个非易失性存储单元。
