摘要:
In a nonvolatile semiconductor memory device having n (n is an integer of two or more) electrode films stacked and having charge storage layers provided above and below each of the electrode films, when data “0” is written by injecting electrons into the charge storage layer on a source line side of a memory cell of the number k (k is an integer of 1 to (n−1)) as counted from an end on a bit line side in a selected semiconductor pillar, positive program potential is given to the electrode film of the number 1 to k as counted from the bit line side, and 0 V is given to the electrode film of the number (k+1) to n, therewith positive potential is given to the bit line and 0 V is given to the source line.
