摘要
A nonvolatile latch circuit according to the present invention includes: a latch operating unit in which outputs of cross-coupled connected inverter circuit and inverter circuit are connected via a series circuit which includes a transistor, a variable resistance element, and a transistor in this order, and store and restore in a latch state are controlled by control terminals of the transistors; and a comparator circuit which compares a signal obtained by amplifying the value of the sum of potentials at both ends of the variable resistance element with the logic state of the latch operating unit, wherein writing to and reading from the variable resistance element are repeated until an output of the comparator circuit indicates that normal write operation has been performed.
