Memory circuits used in computer systems may have different operating modes. In a retention mode, a voltage level of an array power supply node coupled to memory cells included in the memory circuit is reduced to a level sufficient to retain data, but not to perform read and write operations to the memory cells. A power converter circuit may be configured to generate the retention voltage level, and adjust the retention voltage level using a leakage current of dummy memory cells included in the memory circuit.
