ABSTRACT:
A nonvolatile storage device includes a plurality of bit lines21arranged in a column direction on a substrate; a plurality of word lines35arranged in a row direction on the substrate; a memory cell array20having a plurality of memory cells31, where a store state of each of the memory cells31changes according to an electric signal relatively applied to the word line35and the bit line21; a word line selection unit having a needle51relatively movable with respect to the substrate which comes into contact with one word line35, setting the word line35in contact with the needle51to a selection state; and a sense amplifier48detecting through the bit line an electrical signal exhibiting the store state of the memory cell31to be connected to the word line.
