Abstract:
A resistance change memory device including: a cell array having a resistance change type of memory cells disposed at the cross-points of word lines and bit lines, the resistance value of the memory cell being reversibly settable; a word line driver circuit configured to apply a selecting drive voltage to one selected in the word lines; and a bit line driver circuit configured to drive multiple bit lines in such a manner that a set mode and a reset mode are set simultaneously for multiple memory cells selected by the selected word line, the set mode being for changing a selected memory cell from a first resistance state into a second resistance state while the reset mode is for changing a selected memory cell from the second resistance state into the first resistance state.
