Method for combining logic-based circuit units and memory-based circuit units and circuit arrangement

Method for combining logic-based circuit units and memory-based circuit units in a circuit arrangement, in which different supply voltage swings are provided, having the following steps:

• a) providing at least one supply voltage potential for at least one logic-based circuit unit;
• b) providing at least one ground potential for the logic-based circuit unit, in order thus to provide a supply voltage swing for the logic-based circuit unit;
• c) providing at least one supply voltage potential for at least one memory-based circuit unit;
• d) providing at least one around potential for the memory-based circuit unit, in order thus to provide a supply voltage swing for the memory-based circuit unit;
• e) providing a signal voltage swing, which is set between a signal voltage minimum value and a signal voltage maximum value and is applied both to the logic-based circuit unit and to the memory-based circuit unit;
• and
• f) setting at least one ground potential difference between the at least one ground potential and a reference around potential in such a way that the logic-based circuit unit and the memory-based circuit unit are supplied with at least one supply voltage swing, and that the signal voltage swing is provided without a supply voltage swing of the circuit units being exceeded, wherein the signal voltage swing is provided in the range between 0.4 V and 0.8 V, a signal voltage swing average value being set in such a way that the signal voltage maximum value does not exceed 1.0 V.
