Abstract

PURPOSE:To facilitate version management by storing identification data which identifies the data to be stored and the correction data which secures the coincidence between the check data for said data to be stored in the identification data. CONSTITUTION:The identification data which identifies the data to be stored is stored together with the correction data which secures the coincidence between the check data for said data to be stored and the identification data. Thus coincidence is secured between the check sum value and the version No. of a ROM and this check sum value obtained by a ROM writer, etc., means directly the version No. of the ROM. As a result, the ROM management is extremely facilitated for ROM managers.
