Title:
有機分子メモリ
Document Type and Number:
Japanese Patent JP5739042
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an organic molecular memory controlling current flowing through a memory cell, and having a stable operation and high reliability.SOLUTION: An organic molecular memory of an embodiment includes: a first electrode; a second electrode formed of a material different from the material of the first electrode; and an organic molecular layer which is provided between the first electrode and the second electrode and in which one end of a resistance change-type molecular chain constituting the organic molecular layer is chemically bonded to the first electrode and a gap is present between the other end of the resistance change-type molecular chain and the second electrode. When the one end of the resistance change-type molecular chain is a thiol group, a region chemically bonded to the one end, in the first electrode comprises gold (Au), silver (Ag), copper (Cu), tungsten (W), a tungsten nitride (WN), a tantalum nitride (TaN) or a titanium nitride (TiN), and a region facing the other end, in the second electrode comprises tantalum (Ta), molybdenum (Mo), a molybdenum nitride (MoN) or silicon (Si).
