    • PURPOSE: A multi-valued logic device including a nonvolatile memory device is provided to improve reliability by using a multilevel cell nonvolatile memory device with the small number of bits. CONSTITUTION: A multi-valued logic device stores a multilevel signal according to a write signal and outputs the multilevel signal according to a read signal. A conversion unit(110) converts the multilevel signal into a plurality of partial signals. A plurality of nonvolatile memory devices(NV1,NV2) store the plurality of partial signals. The number of bits of the partial signals stored in the nonvolatile memory devices is smaller than the number of bits of the multilevel signal. A write unit(120) stores the plurality of partial signals in the plurality of nonvolatile memory devices according to the write signal.
