摘要
The present invention relates to a method for operating a PMC memory cell for use in a CBRAM memory array, wherein the PMC memory cell includes a solid electrolyte which is adapted to selectively develop and diminish a conductive path depending on an applied electrical field. The PMC memory cell is programmed to change to a programmed state by applying a programming voltage, and the PMC memory cell is erased to change to an erased state by applying an erase voltage. A refresh voltage is applied to the PMC memory cell at a predetermined time to stabilize the programmed state of the PMC memory cell, wherein the refresh voltage is selected such as that, while applying the refresh voltage, a programming of the PMC memory cell in the erased state to a programmed state is prevented, and that, by applying the refresh voltage, a stabilizing of the programmed state of the PMC memory cell is performed.
