An example memory includes an address control portion, a protection film,
a property deterioration material layer, data storage areas, and bonding
pads. The protection film protects an organic semiconductor layer of a
semiconductor circuit and prevents intrusion of moisture or chemical
molecules in the air, light, or the like, into the organic semiconductor
layer. Deterioration of the organic semiconductor layer is started by
breaking the protection film and using a specified means, thus starting
operation of the lifetime period. The property deterioration material
layer contains a material for deteriorating the property of the organic
semiconductor and deterioration of the organic semiconductor layer is
started, for example, by diffusing the material into the organic
semiconductor layer.
