ABSTRACT:
To include a plurality of circuit blocks each including a plurality of nonvolatile memory elements arranged in the X direction, a plurality of comparing circuits that are respectively allocated to the nonvolatile memory elements, and a determining circuit that is commonly allocated to the comparing circuits. The nonvolatile memory elements included in a predetermined circuit block among the circuit blocks are arranged in a first area. The comparing circuits and the determining circuit included in the predetermined circuit block are arranged side by side in the X direction in a second area that is located in the Y direction with respect to the first area. With this arrangement, because the circuit block becomes a shaped block, even when a plurality of circuit blocks are repeatedly arranged, it is possible to realize a further reduction of the chip area.
