PROBLEM TO BE SOLVED: To provide an organic molecular memory having stable operation and high reliability by controlling a current flowing through a memory cell.SOLUTION: An organic molecular memory of an embodiment includes: a first electrode; a second electrode formed of a material different from that of the first electrode; and an organic molecular layer which is disposed between the first electrode and the second electrode, and in which one end of a variable resistance molecular chain constituting the organic molecular layer is chemically bonded to the first electrode, and a gap exists between the other end of the variable resistance molecular chain and the second electrode. When the one end of the variable resistance molecular chain is a thiol group, a region chemically bonded to one end of the first electrode is gold (Au), silver (Ag), copper (Cu), tungsten (W), tungsten nitride (WN), tantalum nitride (TaN) or titanium nitride (TiN), and a planar region facing the other end of the second electrode is tantalum (Ta), molybdenum (Mo), molybdenum nitride (MoN), or silicon (Si). |
