ABSTRACT:
An integrated circuit having a resistance-based or resistively switching memory cell, and a method for operating a resistively switching memory cell is disclosed. One embodiment is adapted to be put in a low-resistance state by applying a first threshold voltage and in a high-resistance state by applying a second threshold voltage, wherein reading out of the data content from the memory cell is performed by applying a voltage to the memory cell in the range of the first or second threshold voltage or a higher voltage.
