Organic molecular memory

An organic molecular memory comprising:

• a first memory string extending in a first direction;
• a second memory string extending in the first direction;
• a third memory string extending in the first direction;
• a first wire extending in a second direction intersecting the first direction, and electrically connected to the first memory string and the second memory string in the first direction;
• and
• a second wire extending in the second direction, electrically separated from the first wire, and electrically connected to the third memory string in the first direction, wherein each of the first memory string, the second memory string, and the third memory string includes:
• a first electrode including a first part,
• a second electrode provided between the first electrode and the first wire or between the first electrode and the second wire,
• a third electrode,
• an organic molecule layer provided between the first electrode and the second electrode, extending in the first direction, and including a first molecule and a second molecule provided between the first molecule and the second electrode, and
• a conductive polymer, wherein
• the first molecule is provided between the first part and the third electrode in a direction intersecting the first direction, and
• the conductive polymer is provided at one of a position between the first part and the first molecule and a position between the third electrode and the first molecule.

An organic molecular memory comprising:

• a first electrode;
• a second electrode;
• a third electrode;
• and
• an organic molecule layer provided between the first electrode and the second electrode, extending in a first direction from the first electrode toward the second electrode, and including a first molecule and a second molecule provided between the first molecule and the second electrode, wherein
• the third electrode faces the first molecule,
• the first molecule and the second molecule are each a cyclic compound, which has a central skeleton containing a metal element,
• the cyclic compound is a naphthalocyanine, an anthrocyanine, a tetralocyanine, or a pentlocyanine, and
• the metal element is one metal element selected from a group consisting of manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), and zinc (Zn).
