Abstract
To provide a control circuit capable of reliably generating a reference potential while suppressing increase in power consumption and cost. Provided is a control circuit that performs control to separate from a sense amplifier a second reference element set to a predetermined resistance state, which is different from a first reference element set to a predetermined resistance state and connected to the sense amplifier in generating a reference potential used for data read through the sense amplifier from a memory cell.
