Integrated circuit provided with a substrate and memory transponder

Abstract

The integrated circuit ( ) has a substrate and a memory with a first memory unit ( ) containing organic material. The first memory unit ( ) has a first ( ) and a second electrode ( ), which are in the non-programmed state electrically connected by an interconnection ( ). On programming, the interconnection ( ) is at least partially broken in that it is locally heated. This heating can be effected electrically and optically. By preference the first memory unit ( ) is integrated in a first layer ( ) of organic material, which also has a first electrode ( ) of the integrated circuit ( ). The integrated circuit ( ) can be used in a transponder which is electrically programmable. In the method of programming, the local heating is effected electrically, by applying a voltage across the first memory unit ( ).
