Abstract
A program updating system having correction storage units and methods thereof are described. The control unit checks the first setting section of the first storage unit to determine whether the first setting data associated with the second storage unit is stored in the first setting section. When the first setting data is stored in the first setting section, the control unit reads the first setting data and writes the first setting data to the second storage unit. The first setting data includes a first correcting address and a first correcting code corresponding to the first correcting address. The second storage unit stores a first setting data transmitted from the first setting section. The control unit compares an executed address of the original program with the first correcting address. When the executed address is identical to the first correcting address, the control unit replaces a first error code corresponding to the executed address with the first correcting code.
