Abstract
In an one-chip microcomputer used in an automobile, error correction code data is added to corresponding user data, and then the resulting user data is stored into an EEPROM to correct an 1-bit error contained in this user data. The one-chip microcomputer is arranged by an electrically erasable memory for temporarily storing thereinto externally supplied user data and ECC (error correction code) data corresponding to the user data; a program storage memory for previously storing thereinto a program; and a CPU (central processing unit) for reading the program from the program storage memory so as to produce the ECC data based upon the externally supplied user data, and for sequentially correcting errors contained in the externally supplied user data by using the produced ECC data corresponding to the externally supplied user data.
