Abstract
The present technique relates to a non-volatile memory circuit ensuring a small size and low power consumption while maintaining stable write. A slave latch is provided in an NVDFF, and magnetoresistive elements are connected to the slave latch. A store operation for writing information stored in the slave latch to the magnetoresistive elements is performed before power interruption, and a restore operation for reading out information stored in the magnetoresistive elements to the slave latch is performed at a time of return. The store operation and the restore operation use different paths between the slave latch and the magnetoresistive element. The present technique is applicable to a non-volatile memory circuit.
