Abstract:
In various aspects, a method for operating a memory cell arrangement is provided, including: providing a set of supply voltages to one or more sets of memory cell drivers to write one or more memory cells of the memory cell arrangement; wherein providing the set of supply voltages includes: ramping a first supply voltage of the set of supply voltages to a first predefined output voltage level, and ramping a second supply voltage of the set of supply voltages to a second predefined output voltage level dependent upon the first supply voltage, the first predefined output voltage level and the second predefined output voltage level defining a first predefined ratio, wherein, during the ramping of the first supply voltage and of the second supply voltage, a first ratio of the first supply voltage to the second supply voltage is substantially equal to or less than the first predefined ratio.
