Claim 11:
12. A method for operating a three-dimensional semiconductor device comprising strings including a data storage pattern including a ferroelectric material, selection lines, and word lines connected to the strings, the method comprising:
applying a first voltage to a first bit line connected to a first string including a first memory cell in which data is to be stored among the strings;
applying a second voltage to a first selection line corresponding to the first string;
applying a third voltage to a selection word line corresponding to the first memory cell among the word lines; and
applying a fourth voltage to a first word line corresponding to a second memory cell among the word lines, the second memory cell being immediately adjacent to the first memory cell in the first string;
wherein the first voltage is different from the fourth voltage, the fourth voltage is higher than a voltage applied to a second bit line that is adjacent to the first bit line, and the voltage applied to the second bit line is higher than the second voltage.
