To make it possible to write a defective part address and a correcting program to a nonvolatile memory while the nonvolatile memory is mounted by providing a means which stores the head address of the inputted defective part and the correcting program for the defective part in the nonvolatile memory.

This equipment is equipped with the means which stores the head address of the inputted defective part and the correcting program for the defective part on the nonvolatile memory, a means which executes the correcting program instead of the defective part according to those head address and correcting program, etc. For example, the microcomputer of a VCR is equipped with a CPU 1 which controls respective parts of the VCR, a ROM 2 storing its program, etc., and a RAM 3 storing necessary data. This RAM 3 is provided with an area E1 used as a defective part address setting address, an area E2 used as an interruption vector table, an area E3 for storing the correcting program, etc.
