Abstract:
According to one embodiment, a resistance change memory device comprises a memory cell array in which a plurality of resistance change storage elements each to store one of multiple resistance states as data represented in two or more bits are arranged, and a read unit to read the data of a selected one of the storage elements. In reading the data of the storage element, the read unit, selecting one at a time, applies multiple types of constant voltages to the storage element.

Claim (Index 14):
The resistance change memory device according to  claim 13 , wherein the read unit first selects a first reference voltage corresponding to a middle threshold resistance of a plurality of threshold resistances to determine which of the multiple resistance states the data of the storage element is, and a first constant voltage, and\n wherein if the voltage on a bit line, for supplying a voltage to the storage element, when reading after applying the first constant voltage exceeds the first reference voltage, the read unit selects a second reference voltage, higher than the first reference voltage, as a reference voltage corresponding to a threshold resistance higher by one step than the middle threshold resistance and applies, as a constant current, a maximum current that is a maximum current outside a forbidden region that is a set of phase transition points indicating operation points at which a phase transition occurs in the storage element so as to read, and wherein setting is made such that the operation point of the storage element when reading while applying the maximum current avoids the forbidden region.
