Abstract
A control circuit capable of generating a reliable reference potential while suppressing increase in power consumption and cost. A control circuit causes write processing to be performed individually for a first reference element set to a first resistance state in generating a reference potential used for reading data from a memory element, and a second reference element different from the first reference element, the second reference element being set to a second resistance state different from the first resistance state in generating the reference potential.
