Data correction circuit and semiconductor integrated circuit

A semiconductor integrated circuit including a processor, the integrated circuit comprising:

• a non-rewritable nonvolatile memory in which data for the processor is stored;
• and
• a memory control circuit configured to control access to the nonvolatile memory, the control circuit comprising:
• an address register configured to store an address indicating a correction point of the nonvolatile memory;
• a data register configured to store correction data for the nonvolatile memory;
• a comparator configured to compare a read address indicating a read position from the nonvolatile memory and the address stored in the address register, and to output a comparison result of the read address and the address stored in the address register;
• and
• a selector configured to select one of read data from the nonvolatile memory and the correction data stored in the data register, according to the comparison result, and to output the selected data.
