摘要

According to one embodiment of the present invention, an integrated circuit is provided which includes a plurality of resistivity changing cells. At least two resistance ranges are assigned to each resistivity changing cell, each resistance range defining a possible state of the resistivity changing cell. The integrated circuit is operable in a cell initializing mode in which initializing signals are applied to the resistivity changing cells. The strengths and durations of the initializing signals are chosen such that the resistance of each resistivity changing cell is shifted into one of the resistance ranges assigned to the resistivity changing cell.
