MEMORY CONTROL CIRCUIT, MEMORY, AND MEMORY CONTROL METHOD

A memory control circuit includes an input circuit that receives data to be written to a storage having multiple nonvolatile memory cells, and a control circuit, when a second number of bits that are included in a first bit string and having a first number of bits and have a second logical value different from a first logical value equal to initial values stored in the multiple nonvolatile memory cells is equal to or smaller than a first threshold, writes the first bit string and the first additional value to the storage, and that associates, when the second number of the bits is larger than a second threshold larger than the first threshold, a second bit string obtained by reversing logical values of all the bits of the first bit string with a second additional value and writes the second bit string and the second additional value to the storage.
