ABSTRACT:
A nonvolatile semiconductor memory device has a plurality of memory strings each including a plurality of electrically rewritable memory cells serially connected. The memory string includes a columnar semiconductor portion extending in the vertical direction from a substrate, a first charge storage layer formed adjacent to the columnar semiconductor portion and configured to accumulate charge, a first block insulator formed adjacent to the first charge storage layer, and a first conductor formed adjacent to the first block insulator.
